What are Newton's 3 laws of motion?

Newtons first law states that is an object is moving it will continue to do so in a constant direction and uniform velocity unless acted upon by an external force.Newtons second law states that the change in momentum per unit time is directly proportional to the resultant force acting on the body, and occurs in the same line of action as the force.Newtons third law states that wherever there is an action there is an equal and opposite reactions opposing it.
