What is Newton's second law of motion?

• The acceleration of an object is constant regardless of the net force applied.

• 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 directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).
