Understanding Gravitational Time Dilation and Relativity

What concept explains why your feet age slightly more than your head over a lifetime?

• Quantum mechanics

• Special relativity

• Newton's laws of motion

• Gravitational time dilation

What principle states that freefall in a gravitational field is indistinguishable from floating in space?

• Equivalence principle

• Uncertainty principle

• Pauli exclusion principle

• Heisenberg principle

What analogy is commonly used to depict the curvature of space and time in general relativity?

• Balls-on-rubber-sheet

• String theory

• Quantum foam

• Wave-particle duality

What is the primary cause of gravity according to general relativity?

• Nuclear forces

• Curvature of time

• Electromagnetic forces

• Curvature of space

What is the simplest possible clock used in Einstein's thought experiments?

• Sundial

• Pendulum clock

• Photon clock

• Atomic clock

What axiom of special relativity states that the speed of light is constant for all observers?

• Constancy of the speed of light

• Equivalence principle

• Uncertainty principle

• Conservation of energy

What effect does acceleration have on time perception according to the equivalence principle?

• Time appears to slow down

• Time appears to speed up

• Time becomes irrelevant

• Time remains constant

In the rotating space station example, what happens to the time of the stationary clock compared to the rotating one?

• The stationary clock ticks more

• The rotating clock ticks more

• Neither clock ticks

• Both clocks tick the same

What is a better question to ask than 'why does gravity slow time'?

• Why does slowed time cause gravity

• Why is space curved

• Why does gravity exist

• Why is time constant
