# What is Newton's second law of motion?

Newton's second Law of Motion states predicts the behavior of objects for which all objects are balanced. This law is based around equilibrium. The Second Law of Motion explains objects that are not balanced.

 Newton's 2nd law of motion states that the direction of the force vector is the same as the direction of the acceleration vector. Thus, F = ma. http://www.kgbanswers.com/what-is-newtons-second-l...
Newton's second law of motion states that force is equal to that object's mass multiplied by its acceleration, or f=ma.
This explains how the velocity of an object changes when it is subjected to an external force. The law defines a force to be equal to change in momentum (mass times velocity) per change in time.
