物理state newton's second law of motion

网友回答

Newton's second law of motion:
The rate of change of momentum is proportional to the imposed force and goes in the direction of the force.
More specifically:
The acceleration a of a body is parallel and directly proportional to the net force F acting on the body,is in the direction of the net force,and is inversely proportional to the mass m of the body,i.e.,F = ma.
