Physics 211, Quiz 11

Question 1:

The spaceship Enterprise coasts through space with constant velocity. Its engines are off.

Describe the total force on the ship. 

  Answer:  The velocity is constant, so the ship experiences no acceleration.
           So, by Newton's Second Law,

                          F = ma = 0   ->  F = 0
