Answer:
A. something pushes or pulls it to a stop
Explanation:
According to Newton's first law of motion, An object at rest or in motion will continue to be in that state unless an external force acted on it. A body at rest will continue to be in such position until a force is exerted on it .
A body in motion is moved by a particular force, the only way that body in motion can be altered is if it is acted upon by an unbalancing force. Example consider throwing a ball to the air. According to Newton's law the ball will always be in uniform motion unless an opposing or unbalanced force which is the gravitational force act on it . The ball is been pulled by an unbalanced gravitational force .
The Newton first law is also known as the law of inertia .
