Question

If the net force on a moving object is zero, the object is moving with a constant non-zero

• A. acceleration
• B. impulse
• C. velocity

Answer 1

The correct option is C velocity

A force, F, applied to an object causes an acceleration, a, which we know from Newton's 2nd law:

F = m⋅a

or
$a=F/m$

Acceleration is the change of velocity per unit time, so if there is no force, all we know is that the acceleration is zero. Therefore, the velocity is not changing. If the object was already moving, then it will just keep moving with constant velocity.
