Select the option that explains the phrase "all motion is relative, there is no absolute motion." a) Relative motion refers to motion measured relative to some inertial frame. Absolute motion refers to motion measured in the absolute frame, which is defined to be at rest according to all observers in the universe. However, since the laws of motion are the same in all inertial frames, there is no frame that all observers agree is at rest. Therefore, all motion is...

Which of the following statements are IMPOSSIBLE? Choose all that apply. The rocket's speed was measured to be 0.65c. The rocket's rest length is 300 m. An observer flying by measured the rocket to be 321 m long. A rocket flying away from the Sun at 0.78c measured the speed of the photons (particles of light) emitted by the Sun to be c. An inertial reference frame had an acceleration of 0 m/s2.The proper time interval between two events was...
