What are the three factors needed for Newton's Second Law?

Newton's second law of motion is also known as law of acceleration.

Force, mass and acceleration are the three factors needed two explain the law.

Explanation:

This law states that if there is an unbalanced force acted upon an object (either in rest or in motion) the force causes an acceleration. The acceleration is directly proportional to the force.

F (net) α a, the proportionality constant is the mass of the object.

Another definition for the law is

F (net) = m. a where m stands for mass and a is acceleration.
