LH Relativity Review

The speed of light is constant in all frames of reference.

• True

• False

One of the most startling consequences of time dilation is that a moving clock ______________ relative to a stationary observer.

• Speeds up

• Slows down

When you approach a light source, the light from that source has a speed 

• greater than c. 

• less than c. 

• equal to c.
  

We do not usually observe relativistic effects in our daily lives because 

• we 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. 

Based on the concepts of Special Relativity time travel is...

• not possible

• possible only in the ability to travel into the past.

• possible only in the ability to travel to the future.

• possible to travel either forward or backward in time.

We are able to see into the past.

• True

• False

What is the equivalence principle? 

• gravity and acceleration are the same thing

• constant speed and at rest are the same thing

• gravity is curvature of space

• gravity and constant velocity are the same thing

According to Newton, gravity was a force.... According to Einstein, gravity is a ________.  

• force

• curvature

• mystery

• constant velocity

Which of these provides the best analogy for what massive objects do to spacetime?  

• coat hanger in the closet

• bowling ball on a rubber sheet

• car driving in a circle

• tennis ball in the dryer

During what rare event was Relativity confirmed?

• Total Solar Eclipse

• Total Lundar Eclipse

• Summer Solstice

• Halley's Comet
