- 1. Multiple ChoiceWhich of the following statements is not true according to the theory of relativity?As an object increases speed its mass increases.As an object increases speed its length increases.As an object increases speed its kinetic energy increases.As an object increases speed its momentum increases.
- 2. Multiple ChoiceCompared to clocks in a stationary reference frame moving clocks runfasterslowerat the same rate
- 3. Multiple ChoiceWhen you approach a light source, the light from that source has a speedgreater than c.less than c.equal to c.
- 4. Multiple ChoiceWe do not usually observe relativistic effects in our daily lives becausewe are moving at speeds much less than c.we are much larger than atoms.we are much heavier than elementary particles.we are much lighter than stars.
- 5. Multiple ChoiceWho was the creator of a special theory of relativity? It showed calculations of time and motion.Albert EinsteinHitlerNazis
- 6. Multiple ChoiceAs an object approaches the speed of light, time for that object speeds up, and it ages more quickly.TrueFalse
- 7. Multiple ChoiceWhat does the relativity of simultaneity say?Two events may occur at the same time in one reference frame, but not another.If two events occur at the same time in one reference frame, they will occur at the same time in all reference frames.

- 16. Multiple ChoiceOne of the most startling consequences of time dilation is that a moving clock ______________ relative to a stationary observer.Speeds upSlows down
- 17. Multiple ChoiceIf you travel at the speed of light a second can be observed to last forever.TrueFalse
- 18. Multiple Choice
There are two clocks one is stationary on the earth the other is traveling close to the speed of light around the earth. If we put the clocks back together after the second clock makes it back from its trip, the times are compared. What do you expect to occur?
More time elapsed on the stationary clock
More time elapsed on the traveling clock
No time has changed between them
- 19. Multiple Choice

The muon detection experiment helped confirm one aspect of special relativity, namely that:
to a muon distance was contracted.
muons are created in the upper atmosphere.
muons are relatively short-lived.
fewer muons reach the ground than expected.
- 22. Multiple Choice
The two postulates of special relativity are:
