Special Relativity

The speed of light (c) =

• 3 x 10⁸ miles/hour
• 3 x 10⁸ meters/second
• 3 x 10⁸ kilometers/hour
• none of these

The special theory of relativity was derived by:

• Galileo
• Newton
• Einstein
• Sitter

A postulate is something that is accepted as true at the beginning of a logical article.

• True
• False

How many postulates are there in the special theory of relativity?

• 1
• 2
• 3
• 4

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

• True
• False

If you travel at the speed of light a second can be observed to last forever.

• True
• False

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
