# Postulates of the Special Theory of Relativity

Not what you're looking for?

1. State and explain the postulates of the special theory of relativity.

2. Suppose a person riding on top of a freight car shines a searchlight beam in the direction in which the train is traveling. Compare the speed of the light beam relative to the ground when:

a.The train is at rest.
b. The train is moving.

How does the behavior of the light beam differ from the behavior of a bullet fired in the same direction from the top of the freight car?

3. Define the following terms:

a. Time dilation.
b. Simltaneity
c. Length contraction
d. Mass-energy equivalence

4. What does the equation E = mc2 mean?

5. A rectangular billboard in space has the dimensions 10 meters by 20 meters. How fast and in what direction with respect to the billboard would a space traveler have to pass for the billboard to appear square?

6. How long would a meter stick appear if it were traveling like a properly thrown spear at 99.5 percent of the speed of light?

7. State and explain the principle of equivalence.

1. State and explain the postulates of the special theory of relativity.
Solution:
First postulate: The laws of physics have the same form in all inertial reference frames.
Second postulate (constancy of speed of light): Light propagates through empty space with a definite speed c independent of the speed of the source or observer.
2. Suppose a person riding on top of a freight car shines a searchlight beam in the direction in which the train is traveling. Compare the speed of the light beam relative to the ground when:

a. The train is at rest.

b. The train is moving.

How does the behavior of the light beam differ from the behavior of a bullet fired in the same direction from the top of the freight car?
Solution:
The speed ...
