Use newton's second law to determine how much force is being applied to an object that is traveling at a constant velocity

Acceleration = rates at which velocity changes.
Constant velocity = when an object moves the same distance every second, aka zero velocity.

Newtons 2nd law = (net force) = (mass) × (acceleration)

So, if the acceleration is zero, than the net force must also be zero.
