Relativity

Mass energy relation is

• E=mc2

• E=T+V

• E=T-V

• M=Ec2

1.If you were in spaceship traveling at the speed close to the speed of light (with respect to the earth) you would notice that___________

• your pulse rate is different than normal

• your mass is different than normal

• some of your physical dimensions were smaller than the normal

• none of these effects occur

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

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

• Speeds up
• Slows down

We experience Einstein's Theory of Relativity in our everyday life when we use

• Global Positioning System
• Microwave ovens.
• Toasters
• Graphing Calculators

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

• greater than c. 
• less than c. 
• equal to c.
