Special Relativity and Time Dilation Quiz

What happens to the ticking of a photon clock as it moves relative to a stationary observer?

• It stops ticking.

• It ticks faster.

• It ticks slower.

• It ticks at the same rate.

What is the main effect of time dilation according to Einstein's theory of special relativity?

• Time stops for stationary objects.

• Time speeds up for moving objects.

• Time slows down for moving objects.

• Time remains constant for all objects.

When a clock moves towards you at 50% the speed of light, how do you perceive its ticking compared to when it moves away?

• Ticks are faster when moving towards you.

• Ticks are slower when moving towards you.

• Ticks stop when moving away.

• Ticks are the same in both directions.

How does the ticking of a moving clock compare to a stationary clock from your perspective?

• The moving clock ticks slower.

• The moving clock ticks faster.

• The stationary clock ticks slower.

• Both clocks tick at the same rate.
