Newton's First law
A body continues in its state of rest or constant velocity unless a resultant force acts on it.
Newton's Second Law
The rate of change of momentum of a body is directly proportional to the resultant force acting on it and occurs in the direction of the force. (or F=ma ,where m = mass, a = acceleration and F=resultant force)
Newton's Third Law
If body A exerts a force on body B, then body B exerts an equal but opposite force on body A.
