Newton’s Laws of motion

First Law: Every body continues to be in its state of rest or state of uniform motion in a straight line unless an external force complels it to do so.

Second Law: The rate of change of momentum of a body is directly proportional to the net external force acting on it and the change in momentum takes place in the direction of motion

Third Law: To every action there is an equal and opposite reaction
