Question

Special relativity can be used to study an object in which frame of reference?

A. A frame of reference that is moving at a constant velocity
B. A frame of reference that is speeding up
C. A frame of reference that is moving in a circle
D. A frame of reference that is slowing down

Answer 1

Answer;

A. A frame of reference that is moving at a constant velocity

Explanation;

• Special relativity is applied to reference frames that do no accelerate.
• If a reference frame moves with constant velocity relative to an inertial reference frame, it also is an inertial reference frame.
• There is no absolute inertial reference frame, meaning that there is no state of velocity which is special in the universe.
• Einstein's theories of relativity are a result of the contradiction between Newton's laws of motion and Maxwell's equations.
