Question An object's motion changes(1 point) Responses only if the object is at rest when a force acts upon it. only if the object is at rest when a force acts upon it. when there are no forces acting upon it. when there are no forces acting upon it. only when a nonzero net force is applied to the object. only when a nonzero net force is applied to the object. when the forces acting on the object remain balanced.

The correct response is: only when a nonzero net force is applied to the object.
An object's motion changes only when there is a net force acting on it, according to Newton's first law of motion. If the forces are balanced, the object will either remain at rest or continue moving at a constant velocity.
