Newton`s Second Law
... If an unbalanced force acts on an object then its velocity will change - it will either speed up, slow down, and that includes stopping, or the object will change direction. Newton’s second law explains how this change of velocity, or acceleration, is related to the mass of the body and the force ap ...
