Newton, in His Second Law of Motion, Stated That Any

Newton, in his second law of motion, stated that any body of mass m acted on by a force F:

A) will be given an acceleration a, of size a = F/m.
B) will also have acting on it an equal and opposite force, ma, where F = ma, and a is the acceleration.
C) will remain at rest, unless a second force also acts on the body.
D) moves with a constant velocity, in the direction of the force.
