What is Newton's second law of motion?
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).
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.
