A research project is a student’s independently conducted research that reveals his knowledge and the ability to apply it to solve specific problems. practical problems. The work must be logically complete and demonstrate the student’s ability to competently use special terminology, clearly express his thoughts, and justify proposals.

The objectives of the project are:

  • development of independent skills research activities and their application to solving current practical problems;
  • conducting an analysis of existing theoretical approaches in domestic and foreign science in the field of the research being carried out;
  • conducting independent research on the chosen topic;
  • systematization and analysis of data obtained during the study;
  • project protection.

Defense of a research project - presentation, justification of targeted activities of a theoretical and practical nature in the field of physical knowledge, involving self-study and analysis of literary sources, observations, experiments, analysis of the work done.

As a topic for completing projects, you can choose any topic that is in any way related to physical phenomena and processes; modern equipment and technology. A project, like research, can have both a theoretical and applied focus. The topic may be closely related to areas related to physics: mathematics, computer science, astronomy and others.

Work structure

The structure of the work should be presented as follows:

  • title page;
  • table of contents;
  • introduction;
  • chapters of the main part;
  • conclusion;
  • bibliography;
  • applications.

The title page is the first page of a research paper and is filled out according to certain rules. The full name is indicated in the top field educational institution, on the basis of which the research is carried out. In the middle field is the title of the work, which is written without the word “topic” and is not enclosed in quotation marks. Below, closer to the right edge of the title page, the last name, first name, patronymic of the performer, class, educational institution are indicated, and then the last name, first name, patronymic of the head, his scientific title (if any) and position, place of work are recorded. The lower field indicates the location of the educational institution and the year the work was written. A sample title page is given in Appendix 1.

The table of contents should be on the second page. It contains the titles of chapters and paragraphs and the pages on which they begin. The headings of the table of contents must exactly repeat the titles of chapters and paragraphs in the text. When designing, the headers of steps of the same level must be placed one below the other. The headings of each subsequent stage are shifted five characters to the right relative to the headings of the previous stage. They all start with a capital letter without a period at the end. Page numbers are fixed along the right edge of the printed field.

The introduction states the problem, relevance, practical significance research; the object and subject of research are determined; the purpose and objectives of the study are indicated; The methods of work are briefly listed. All components of the introduction must be interconnected.

The work begins with a statement of the problem, which determines the direction in the organization of the research, and represents an overview of the state of knowledge in the field under study. By posing a problem, the researcher answers the question: “What needs to be studied that has not been studied before?” Raising questions and identifying contradictions is important in the process of formulating a problem.

Raising a problem involves justifying the relevance of the research. When formulating it, it is necessary to answer the question: why does this problem need to be studied at the present time?

After determining relevance, it is necessary to determine the object and subject of research.

In physics projects, the object of research can be understood as a process towards which cognition is directed, or a phenomenon that generates a problem situation and is chosen for study.

The subject of the study is more specific and provides insight into how new relationships, properties or functions of the object are considered in the study. The subject sets the boundaries of scientific research within a specific study.

The purpose of the research is understood as the final, scientific and practical results that should be achieved as a result of its implementation.

Research objectives represent all the successive stages of organizing and conducting research from beginning to end. As a rule, the purpose of a research work is one, while there are several tasks. Solving a problem allows you to go through a certain stage of research. The formulation of tasks is closely related to the structure of the study, and individual tasks can be set for both the theoretical (review of the literature on the problem) and the experimental part of the study. Objectives determine the content of the study and the structure of the text of the work. The first represents everything that was done during the research.

An important point in the work is the formulation of a hypothesis, which should be a logical, scientifically substantiated, quite probable assumption that requires special evidence for its final approval as a theoretical position.

A hypothesis is considered scientifically valid if it meets the following requirements:

  • does not include too many provisions;
  • does not contain ambiguous concepts;
  • goes beyond the simple registration of facts, serves to explain and predict them, specifically affirming a new thought, idea;
  • testable and applicable to a wide range of phenomena;
  • does not involve value judgments;
  • has the correct stylistic design.

The chapters of the main part are devoted to revealing the content of the work.

The first chapter of the main part of the work is usually built entirely on the basis of analysis scientific literature. In the project it is necessary to give brief description what is known about the phenomenon under study, in what direction it was previously studied. This characteristic is given in a review of the literature on the problem, which is based on the analysis of several works.

In the process of presenting the material, it is advisable to reflect the following aspects:

  • define and clarify the terms and concepts used in the work;
  • outline the main approaches, directions of research on the problem under study, identify what is known on this issue in science and what is not, what has been proven, but not fully and accurately enough;
  • identify the types, functions, structure of the phenomenon being studied;
  • list the features of the formation (factors, conditions, mechanisms, stages) and manifestations of the phenomenon being studied.

In general, when writing the main body of a paper, it is advisable to end each section with a brief summary or conclusion. They summarize the material presented and serve as a logical transition to subsequent sections.

The structure of the chapter can be presented in several paragraphs and depends on the topic, the degree of development of the problem, and the type scientific work student.

In subsequent chapters of the work, which are experimental in nature, the rationale for the choice of certain methods and specific research techniques is given, and information about the research procedure and its stages is provided. When describing a methodology, the required data are: its name, author, indicators and criteria, which will subsequently be subject to statistical processing.

The experimental section of the work ends with an interpretation of the results obtained. It is advisable to describe the results in stages, regarding the key points of the study. The analysis of experimental data ends with conclusions. When writing them, the following rules must be taken into account:

  • conclusions must correspond to the objectives;
  • conclusions should be a consequence of this study and not require additional measurements;
  • conclusions should be formulated concisely, without large quantity digital material;
  • conclusions should not contain generally known truths that do not require proof.

A description of what and how the author of the study did to prove the validity of the hypothesis is a research methodology. It must also be described in the text of the work. Next, we present our own data obtained as a result of research activities. The obtained data must be compared with each other and with data from sources contained in the literature review on the problem. After this, the patterns discovered during the research should be formulated. It is necessary to clearly understand the difference between working data and data presented in the text of the work. The research process often produces a large array of numbers (or other data, for example, texts) that do not need to be presented. In the text, numbers or specific examples are used to illustrate the results obtained during the study, on the basis of which conclusions are drawn. Therefore, working data is usually processed and only the most necessary is presented in the text. However, it must be remembered that someone may want to get acquainted with the primary research material. In order not to overload the main part of the work, the most interesting primary material can be included in appendices. The most advantageous form of data presentation is graphical, which makes it as easy as possible for the reader to perceive the text.

The presentation of the content of the work ends with a conclusion, which is a brief overview of the research performed. In it, the author can evaluate the effectiveness of the chosen approach and emphasize the prospects of the research. The conclusion should not be a mechanical summation of the conclusions found at the end of each chapter of the main part. It should contain something new and essential that makes up the final results of the study. Conclusions in the conclusion can summarize the results of the study, according to the order of tasks. Conclusions are, in a way, short answers to questions about how the research tasks were solved. The set of conclusions is proof of the completeness of achieving the goal. The goal can be achieved even if the primary hypothesis turns out to be untenable.

You need to clearly understand the difference between the text of the work and the report on it. The main task of the speaker is to accurately formulate and emotionally present the very essence of the study, succinctly illustrating it with a small amount of brightly, imaginatively designed, easy-to-read illustrative material. During the report, it is unacceptable to read out the work or overload it with “extra” data. To highlight the essence of the study, 5-10 minutes is enough. Everything else, if the audience is interested, is stated in the answers to questions.

At the end, after the conclusion, it is customary to place a list of references, which includes only those works that are referenced in the text, and not all articles, monographs that the author read in the process of performing research work. The appendix contains extensive materials. This includes primary tables, graphs, practical results experimental activities and etc.

Registration of research work

The amount of work may vary, the report is 1-5 pages (depending on the class and the degree of readiness of the student for this type of activity). For text written on a computer, font size 12-14, Times New Roman, regular; line spacing – 1.5; margin size: left – 30 mm, right – 10 mm, top – 20 mm, bottom – 20 mm (when changing the size of the margins, it is necessary to take into account that the right and left, as well as the top and bottom margins must total 40 mm). With correctly selected parameters, an average of 30 lines should fit on a page, and an average of 60 printed characters per line, including punctuation marks and spaces between words.

The text is printed on one side of the page; footnotes and notes are printed on the same page to which they refer (single spaced, in a smaller font than the text).

All pages are numbered starting with the title page; the page number is placed at the top center of the page; There is no page number on the title page. Every new section(introduction, chapters, paragraphs, conclusion, list of sources, appendices) starts on a new page.

Between the section title (chapter or paragraph headings) and the following text, you need to skip one line, and after the text, before the new heading, two lines. The title is located in the middle; there is no period at the end of the title.

The title of the chapter is printed in bold in capital letters, the title of paragraphs is in capital letters, the titles of chapters and paragraphs are highlighted from the text by adding additional spacing. The serial number of the chapter is indicated by one Arabic numeral (for example: 1, 2, 3, etc.), paragraphs are double numbered (for example: 1.1, 1.2, etc.). The first digit indicates belonging to the chapter, the second – its own numbering.

Quotations are often used to confirm one’s own conclusions and to critically analyze a particular position. When quoting, the following requirements must be met:

  • when quoting verbatim, the author's thought is placed in quotation marks and given in that grammatical form, in which it is given in the original source. At the end, a link to the source is made, which indicates the number of the book or article in the list of used literature and the page number where the quotation is located, for example: the designation indicates that the quotation used in the work is on page 123 in the original source at number 4 in the list of references ;
  • When quoting non-verbatim (retelling, presenting the points of view of various authors in your own words), the text is not enclosed in quotation marks. After the thought expressed, it is necessary to indicate in brackets the number of the source in the list of references without indicating specific pages, for example: ;
  • if the text is quoted from another publication, then the reference should begin with the words “Cit. according to...", for example: (Quoted from the book);
  • if a quotation acts as an independent sentence, then it begins with capital letter, even if the first word in the source begins with a lowercase letter and is enclosed in quotation marks. Quote included in the text after subordinating conjunction(what, because, if, because), is enclosed in quotation marks and written with a lowercase letter, even if in the cited source it begins with a capital letter;
  • When quoting, it is allowed to omit words, sentences, and paragraphs without distorting the content of the source text. An omission is indicated by an ellipsis and is placed in the place where part of the text is missing;
  • quotations retain the same punctuation marks as in the source;
  • if the author in the above quotation highlights some words, then he must specifically indicate this in parentheses, for example: (underlined by me - F.I. or (our italics - F.I.);
  • there are two or three links to the same source on one page, then serial number indicated once. Further in square brackets it is customary to write [Ibid.] or when quoting [Ibid., p. 309];
  • All citations and references in the text of the work must be formatted identically.

Digital research data are grouped into tables, the design of which must meet the following requirements:

  • the word “Table” without abbreviation and quotation marks is written in the upper right corner above the table itself and its title. Tables are numbered in Arabic numerals without a number sign and a period at the end. If there is only one table in the text, then it is not assigned a number and the word “table” is not written;
  • The numbering of tables and figures can be continuous throughout the entire text of the work or independent in each section. It is then presented in levels like chapters and paragraphs. The first numbering option is usually used in works that are small in volume and structure. The second is preferable if there is a detailed structure of the work and a large amount of visual material;
  • the name of the table is located between its designation and the content itself, written with a capital letter without a dot at the end;
  • When transferring the table to the next page, the headings of the vertical columns of the table should be numbered and when transferring the table to the next page, repeat only their number. First, above the table on the right, place the words “Continuation of Table 8”;
  • the name of the table and its individual elements should not contain abbreviations or abbreviations not previously specified in the text of the work.

As illustrations in research papers, drawings, diagrams, graphs, diagrams, which are discussed in the text, can be used. When designing illustrations you should remember:

  • All illustrations must be numbered. If the work presents different types of illustrations, then the numbering is separate for each type;
  • Only those illustrations to which there are direct references such as “the above is confirmed by the drawing...” are placed in the text of the work. The rest of the illustrative material is located in the appendices;
  • numbers of illustrations and their titles are written below the image, indicated in Arabic numerals without a number sign after the word “Fig.”;
  • Various inscriptions are allowed on the illustration itself, if space permits. However, they are more often used symbols, which are deciphered below the image;
  • Diagrams of all types must express the features of the main and auxiliary, visible and invisible parts, connections of the depicted objects or process.

Applications can be varied in content. When preparing them, you should take into account the general rules:

  • appendices are designed as continuations of the main material on subsequent pages. If the volume or format is large, applications are drawn up as a separate block in a special folder, on the front side of which the heading “Appendices” is given, and then all elements of the title page of the research work are repeated;
  • each application must begin on a new sheet, must be numbered in the upper right corner, write: Annex 1 (2, 3 ... etc.) without a period at the end;
  • each application has a thematic heading, which is located in the middle of the line;
  • the numbering of pages on which appendices are given should continue the general numbering of pages of the main text;
  • The connection between the main text and appendices is carried out through links using the word “see”. The indication is usually enclosed in parentheses, for example: The data (see Appendix 1) can be grouped as follows.

The bibliography of a research paper consists only of those sources that are referenced in the text. When compiling a list in scientific circles, it is customary to use an alphabetical method of grouping literary sources, where the names of authors or titles (if there are no authors) are placed in alphabetical order.

The bibliographic list is drawn up in accordance with GOST 7.1-2003. “Bibliographic record. Bibliographic description of the document. General requirements and rules of compilation."

Rules for the design of bibliographic lists:

  • For books of one or more authors, the surname and initials of the authors (dot), the title of the book without quotes with a capital letter (dot and dash), place of publication (dot, colon), publisher without quotes (comma), year of publication (dot and dash) are indicated. , the number of pages in a book with a capital "c" at the end (period). Example: Perret-Kpermon A. N. Role social interactions in the development of children's intelligence. – M.: Pedagogy, 1991. – 248 p.
  • For a collection compiled by two or three authors, indicate the name of the collection (one slanted line), followed by the word “Compiled.” (dot) initials and surname of the compilers (dot, dash), place of publication (dot, colon), name of the publisher (without quotes, comma), year of publication (dot, dash), number of pages in the collection with a capital letter “s”. For example: Advice to the manager / Comp. A. N. Zotov, G. A. Kovaleva. – Sverdlovsk: Middle-Ural. book publishing house, 1991. – 304 p.
  • When preparing a collection with a group of authors under a general editorship, the name of the collection is indicated (one slanted line), then there may be 2 options: 1) the word “Compiled.” and a list of compilers (semicolon), the word “Ed.” (dot), initials and surname of the editor (dot, dash), place of publication (dot, colon), publisher (comma), year of publication (dot, dash), number of pages (capital “s”, dot); 2) the word “Ed.” (dot), initials and surname of the editor (dot, dash), place of publication (dot, colon), publisher (comma), year of publication (dot, dash), number of pages (capital “s”, dot). For example: Brief Dictionary Russian language / Comp. I. L. Goretskaya, T. N. Polovtseva, M. N. Sudoplatova, T. A. Fomenko; Ed. V. V. Rozanova. – M.: Russ, language, 1990. – 251 p. Psychology. Dictionary /Under general. ed. A. V. Petrovsky, M. G. Yaroshevsky. – 2nd ed. – M.: Politizdat, 1990. – 494 p.
  • For articles in the collection, indicate the surname and initials of the author (dot), title of the work (two oblique lines), title of the collection (dot, dash), place of publication (dot, dash), capital letter “C” (dot), number of the first and last pages (dot). Example: Leontyev A. Ya General concept about activities // Reader on developmental psychology. Ed. D. I. Feldstein - M.: Intern. Pedagogical, Academy, 1994. – P. 112-121.
  • For articles in the journal, indicate the surname and initials of the author (dot), title of the article (two oblique lines), name of the journal without quotes (dot, dash), year of publication (dot, dash), journal number (dot, dash), capital letter " C" (dot) page (dot). Example: Einstein V. Examinees and examiners // Higher education in Russia. – 1999. – MZ. – P. 34-42.

Project activity of students is one of the methods of developmental (personally-oriented) training, aimed at developing independent research skills (posing a problem, collecting and processing information, conducting experiments, analyzing the results obtained), which contributes to the development of creativity And logical thinking, brings together the knowledge gained during educational process, contributes to the formation of some professional competencies. A list of topics for implementing projects in various forms is proposed.

INTRODUCTION.

Problem : Understand whether we need to take into account the braking distance when we use transport or cross the road in front of transport.

Why can’t you cross the road in front of nearby traffic? What distance do they consider safe from a moving vehicle? How can we explain the high percentage of road injuries and traffic accidents?

The answers to these and many other questions related to the movement of bodies are given by the laws of mechanics.

Relevance of the topic.

Many of those who are currently studying at school will in the future become drivers or pedestrians who must know that braking distance depends on the initial speed and the coefficient of adhesion of the tires to the road.

The main goal of this project:

Tasks:

To achieve our goals, we worked on this project in the following areas:

Hypothesis. The braking distance depends on the speed and the coefficient of adhesion of the tires to the road.

Practical significanceconsists in applying the dependence of the braking distance on speed and on the coefficient of adhesion of the tires to the road. It is also necessary to take this into account in everyday life.

Scientific interest is that in the process of studying this issue, some information was obtained about practical application braking distance phenomena.

2.What is braking distance (a little theory)

2.1 Braking distance of a car.

Braking distance is the distance covered by a car from the start of braking to a complete stop.

The beginning of the braking distance is the moment when the car's braking system is activated, and its end is the moment the car comes to a complete stop.

It goes without saying that a moving car at high speed will not be able to stop instantly. He will walk some distance before stopping. Thus, a modern car on a highway at a speed of 100 km/h travels up to 28 m every second. It is clear that a certain distance is needed to stop it completely.

Its value is directly dependent on the speed of movement, the method of braking and road conditions. At a speed of 50 km/h the average braking distance will be about 15 m, and at a speed of 100 km/h about 60 m i.e. four times more.

The braking distance of a car depends on many factors:

1- movement speed

2- road surface

3- weather conditions

4- condition of wheels and brake system

5-braking method

The length of the braking distance is often the decisive factor in a critical situation on the road.

An extra meter traced by tires on the asphalt can cost not only a broken bumper, but also your life.

2.2 Braking distance formula.

There are several formulas for calculating braking distance. They are based on Newton's second law.

The main braking distance of a car can be determined by the formula:

S = V²о/2gµ,

Where:

S - braking distance in meters;

Vo is the speed of the vehicle at the moment of braking, m/sec;

g - gravity acceleration equal to 9.81 m/s 2 ;

µ - coefficient of tire adhesion to the road.

The above formula is only suitable for simultaneous braking of all wheels to the point of skidding.

The formula shows that the braking distance depends only on the speed and coefficient of adhesion of the tires to the road. However, the value of the latter may change depending on the type and condition of the road surface, the type of vehicle tires and the air pressure in them.

2. EXPERIMENTAL RESULTS.

1. Dependence of braking distance on bicycle speed

Table 7

Conclusion: The higher the speed, the longer the braking distance. When driving a car both on a dry summer road and on a slippery winter road, the braking distance and braking time depend on the initial speed, and the braking distance is directly proportional to the square of the initial speed

2. Dependence of braking distanceon the coefficient of tire adhesion to the road.

Conclusion: the coefficient of road adhesion depends on weather conditions. The worse the road, the lower the coefficient and the longer the braking distance.

CONCLUSION.

Many accidents could have been avoided if drivers had followed the golden rule - keep your distance. In our work, we found out what distance should be maintained for our own safety and how to determine the required distance

Now we know exactly what the braking distance depends on. More specifically, braking distance depends on:on the speed and coefficient of tire adhesion to the road.

We conducted a series of experiments, performed approximately the same experiments as scientists, and obtained approximately the same results. It turned out that experimentally we confirmed all the statements we made.

We created a series of experiments to help understand and explain some “difficult” observations.

But most importantly, we realized how great it is to gain knowledge ourselves and then share it with others.

Conclusions:

Research has shown that:

  1. The braking distance of a car depends on speed and oncoefficient of tire adhesion to the road.
  1. To ensure traffic safety in any road conditions, when driving at any speed, the following rule must be observed: the stopping distance must be less than the visibility distance.
  1. When driving a car both on a dry summer road and on a slippery winter road, the braking distance and braking time depend on the initial speed, and the braking distance is directly proportional to the square of the initial speed and the braking time is its first power (t ~ 0);
  1. Since in winter the coefficient of friction of rubber on asphalt decreases, braking distance and braking time increase;
  1. Stopping traffic requires time and space: you cannot cross the road in front of nearby traffic. This should be remembered in order to avoid accidents for both pedestrians and motorists.
