Abstract
The article is considered a methodic for introducing the conception of the light speed as a fundamental constant that shows the invariance of the light speed and the physical meaning of its numerical value. It is advisable to study the foundations of the special theory of relativity on the basic principles – the relativity and invariance of the light speed in a vacuum. During studying the material, such notion as “speed”, “time”, “length”, “impulse”, “energy” are analyzed. Students know the fundamentals of these principles and notion, it is only necessary to clarify them from the relativistic positions. To study the material is proposed by solving problems on the calculation of the mass and length of the body, which moves at a speed of 0.1 to 0.9 speed of light, using the graphs of the ependences m(v), l(v). The proposed method clearly convinces students of the length and weight of the body from its speed relative to the speed of light. This approach activates the cognitive activity of students in the study of this topic, contributes to the formation of a scientifi c view and better understanding of relativistic laws.
