Exploring the Wonders of Relativity

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

• Time appears to pass more quickly for an observer in motion relative to a stationary observer.

• Time appears to pass more slowly for an observer in motion relative to a stationary observer.

• Time is constant for all observers regardless of their motion.

• Time is an absolute quantity that does not change with motion.

What is the formula for time dilation in special relativity?

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

• Perpendicular to the direction of motion

• Parallel to the direction of motion

• In all directions equally

• Length does not change with motion

What is the equation for length contraction?

Which equation represents mass-energy equivalence?

In the context of special relativity, what does the term "simultaneity" refer to?

• The idea that all events occur at the same time for all observers.

• The concept that two events that are simultaneous in one frame may not be simultaneous in another.

• The principle that time is absolute and the same for all observers.

• The notion that time and space are independent of each other.

Which of the following is a consequence of the Lorentz transformation?

• The speed of light is constant in all inertial frames.

• Mass increases with velocity.

• Time and space are absolute.

• Energy is conserved in all frames.

Which of the following describes relativistic momentum?

What happens to the mass of an object as it approaches the speed of light?

• It decreases.

• It remains constant.

• It increases.

• It becomes zero.
