Relativity Quiz

What is the phenomenon called when time appears to move slower for an object moving at high speeds compared to an object at rest?

• Length Contraction

• Time Dilation

• Gravitational Time Dilation

• Lorentz Transformation

According to Einstein's Theory of General Relativity, what is the effect of gravity on time?

• Time speeds up in stronger gravitational fields

• Time slows down in stronger gravitational fields

• Time remains constant regardless of gravity

• Time reverses in stronger gravitational fields

What is the term for the phenomenon where the length of an object moving at a high velocity appears shorter along the direction of motion?

• Time Dilation

• Length Contraction

• Gravitational Time Dilation

• Lorentz Transformation

In the Twin Paradox, one twin travels to space at a high speed while the other stays on Earth. Upon return, which twin is younger?

• The twin who stayed on Earth

• The twin who travelled to space

• Both twins are the same age

• Age difference depends on the distance travelled

Which of the following is a consequence of Einstein's Theory of General Relativity?

• Objects moving at high speeds appear longer

• Time is absolute and the same for all observers

• Gravity is a curvature of spacetime

• Light travels faster in a gravitational field

What is the term for the mathematical transformations that relate the space and time coordinates of two systems moving at a constant velocity relative to each other?

• Time Dilation

• Length Contraction

• Lorentz Transformation

• Gravitational Time Dilation

Which of the following best describes gravitational time dilation?

• Time speeds up as you move away from a massive object

• Time slows down as you move away from a massive object

• Time remains constant regardless of distance from a massive object

• Time reverses as you move away from a massive object

In the context of relativity, what does the term "invariant" mean?

• A quantity that changes with speed

• A quantity that remains constant for all observers

• A quantity that depends on the observer's frame of reference

• A quantity that is zero in all frames of reference
