Relativity Quiz

Which of the following best describes time dilation in the context of 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 is an absolute quantity and does not change.

In the twin paradox, which twin ages more slowly?

• The twin who stays on Earth.

• The twin who travels at a high speed in space.

• Both twins age at the same rate.

• The twin who travels at a low speed in space.

What is a frame of reference in the context of special relativity?

• A stationary point in space.

• A set of coordinates used to measure the position and time of events.

• A moving object.

• A point where time does not change.

Proper time is defined as:

• The time interval measured by an observer in motion relative to the event.

• The time interval measured by an observer at rest relative to the event.

• The time interval that is always longer than improper time.

• The time interval that is always shorter than improper time.

Improper time is defined as:

• The time interval measured by an observer in motion relative to the event.

• The time interval measured by an observer at rest relative to the event.

• The time interval that is always longer than proper time.

• The time interval that is always shorter than proper time.

Which experiment involved clocks on passenger jets to verify time dilation?

• Michelson-Morley experiment.

• Hafele-Keating experiment.

• Young's double-slit experiment.

• Stern-Gerlach experiment.

The equation for time dilation is given by:

• The speed of sound.

• The speed of light in a vacuum.

• The speed of the moving object.

• The speed of the observer.

Which of the following is an example of a proper time interval?

• The time measured by a clock moving with the event.

• The time measured by a clock stationary relative to the event.

• The time measured by any observer.

• The time measured by a clock in a different frame of reference.

Which of the following is an example of an improper time interval?

• The time measured by a clock moving with the event.

• The time measured by a clock stationary relative to the event.

• The time measured by any observer.

• The time measured by a clock in a different frame of reference.
