Question 15

Which statement about forces and motion is correct?

A

If an object is at rest, there cannot be any forces acting on it.

B

If the speed of an object is changing, the resultant force on it must be zero.

C

If an object is moving at a constant velocity, the resultant force acting on it must be zero.

D

If a constant nonzero resultant force acts on an object, it must move at a constant speed.
