The correct statement that applies to a car that changes its velocity over a period of time is:
**A nonzero net force is acting on it.**
When an object's velocity changes, it is undergoing acceleration, which according to Newton's second law of motion, implies that there must be a net force acting on the object. If the net force were zero, the car would not change its velocity; it would either remain at rest or continue moving at a constant speed.
