Special Relativity

Which 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. 

Compared to clocks in a stationary reference frame moving clocks run 

• faster
• slower
• at the same rate

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

• 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. 

Who was the creator of a special theory of relativity? It showed calculations of time and motion.

• Albert Einstein
• Hitler
• Nazis

As an object approaches the speed of light, time for that object speeds up, and it ages more quickly.

• True
• False

What 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.
