Newton's second law states that if a net force acts on an object, it will accelerate in the direction of that net force
. The acceleration of an object is directly proportional
to the force applied on it; that is, a small amount of force will cause a small acceleration. Furthermore, the acceleration of an object is inversely proportional
to its mass; that is, a big object will have a small acceleration and a small object will have a large acceleration, given that the same amount of force is applied. That is summarized in the following equation:
is the net force applied on an object, m
is its mass and a
is its acceleration.
