A train slowing down as it climbs a hill is an example of an inertial frame of of reference.

• True
• False

A train stopped at a station is an inertial frame of reference.

• True
• False

A train moving with a constant speed is an example of an inertial frame of reference.

• True
• False

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. 

In what year did Einstein develop his theory of relativity?

• 1880

• 1905

• 1914

• 1921

Compared to clocks in a stationary reference frame moving clocks run 

• faster
• slower
• at the same rate
