What is Newton's second law of motion?
An object in motion will stay in motion unless acted upon by an equal force.
The acceleration of an object is constant regardless of the net force applied.
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).
The force acting on an object is equal to its mass times its velocity (F = mv).
