Relativity Quiz

Which of the following best describes time dilation in special relativity?

• Time appears to pass more quickly for objects moving at high speeds.

• Time appears to pass more slowly for objects moving at high speeds.

• Time remains constant regardless of the speed of the object.

• Time appears to pass more quickly for objects at rest.

What is the formula for time dilation in special relativity?

Length contraction occurs in which direction relative to the motion of the object?

• Perpendicular to the direction of motion

• Parallel to the direction of motion

• In all directions equally

• Length contraction does not depend on the direction of motion
