Activphysics Activities

Introduction

             The purpose of this activities is to understand the theory of relativity of time and length. In this activities, some of the relativity theories will be simulated in the activities.

Activities

Questions on Relativity of Time

1. The distance of the stationary light clock is shorter than that of the moving clock as shown in picture above.
2. The time of the moving clock is greater relative to a stationary frame of reference than the stationary clock.
3. In the moving frame of reference, the time interval of the light of the moving clock is the same as the stationary clock
4. As the velocity of light clock decreased, the time interval difference will also decrease.
5. delta_t = 1.2 * 6.67 µs = 8.00µs
6. gamma = 7.45 / 6.67 = 1.12

Questions on Relativity of Time

1. The round trip is independent of the velocity
2. The round trip time interval will be longer observed from earth since there will be a value for gamma.
3. It can't be equal since by saying it is equal, it means there is no time dilation.
4. L = 1000 / 1.3 = 769m
