The Working Student Place for Modern Physical Laboratory 108 Abstracts Abstracts Self-oscillations in the Course of General Physics V.A. Aleshkevich, V.M. Akhmetiev In the article consider the example of self-oscillations - the pendulum on the rolling cylinder. From the balance of energy is given simplified evaluation of fluctuation amplitude. Computer modeling of process is displayed in real-time with help of the modern methods of 3D graphics.
Considering of the light absorption in inverse time derives the dipole radiation formula. Thus, the principle equations of Newton's mechanics and time inverse properties of the physical lows let us possible to formulate the principle properties of the dipole radiation without considering Maxwell's equations.
It is informed experience of realization of competition of laboratory works on experimental physics department. For a basis of competition the structure of realization of scientific conferences is put. Stages of preparation of competition are analyzed and are judged perspectives of competition for revealing talented students of physical specialties.
It is possible to investigate a skin effect in the cylinder conductor
(wire) by the modification of its active resistance with the changing
of the frequency of the flowing alternating current.
The original method is described for studying the particles of liquid given by ultrasonic cavitations in the gravitation field of Earth. This lab is recommended as methodic support of division "Statistics Physics" of the General physics course. The Reflection of the Presentations Modern Physicists in Laboratory Practical
Work
The educational laboratory work on molecular physics is submitted, allowing to determine experimentally on the elementary equipment not only specific heat of evaporation of liquid, but also heat transfer, heat radiation and heat capacity of the system. It becomes possible as a result of deep enough mathematical processing of experimental data.
The course operation on physics is offered, where a basis for obtaining input data for calculations are the experimental results retrieved by the students during execution of a laboratory practical work. The Measurement of Gravity Acceleration by Ballistic Method during the
Demonstration Experiment The automated demonstration device for determination of gravity acceleration by ballistic method is described. The apparatus allows measuring of free fall acceleration in vacuum, observing the falling of bodies in the air. There are theoretical foundations of experimental data processing method listed. Experimental results are also presented in the article.
The Installation of Current Distribution in Strip Conductor The description of a lecture demonstration acquainting students with the process of installation the current distribution in a strip conductor after the arrival of a step-liked jump of the total current is given.
The following describes the simple lecture experiment demonstrating the existence of air resistance force for falling objects. The experimental results and theoretical calculations show a good agreement. The experiment takes but a few minutes, is simple to prepare and doesn't require any special equipment.
Two laboratory works on electrodynamics (circuit of constant and alternating current) with use of the personal computer are submitted. The program support is carried out with the help of universal system of modeling "Electronics Workbench 5.12" (EW). To works the methodical description of system EW is applied which is adapted to use in the educational programs. Is developed and within two years the computer testing is successfully applied at the admission and protection by the students of laboratory works. The programs for testing and practical work are placed on server of university "Dubna", that allows to organize remote training.
The paper presents a set of computer laboratory works on physics. They are covered three sections: mechanics, substance's structure and optics. Every laboratory work consists of several stages including admitting to the work (the test), making the computer model of read laboratory plant, carrying out experimental research, defending of the work. Used computer modeling of the real physics processes is so called computing experiment based on mathematical model of the research physical effect.
The organization of laboratory works at the course of automatics and computer facilities with direct use of the personal computer for measurement, flexible multilevel realization of works and control of knowledge of the pupils is examined. The opportunity of similar use of the COMPUTER in other laboratories of a course of general physics is discussed also.
Possible ways of video cameras and video capture devices usage is discussed. Setup for physics demonstrations including PC with video capture and video camera is described. A number of quantitative demonstrations based on created software are proposed.
The experimental sample of the individual student work place has been described. The table construction has a special possibility for many physical experiments with a computer. |
