A) If the net force acting on an object is zero, it does not accelerate.

B) When one object exerts a force on a second object, the first object exerts an equal force on itself in the opposite direction.

C) Acceleration of an object is proportional to net force divided by mass.

D) When you push on an object, it pushes back just as strongly on you.
