This video explains Newton's Laws for A Level Physics.
Normally you start at number 1 and work through to number 3, but in this video I start with Newton's 3rd Law, then Newton's 2nd Law and finally Newton's 1st Law (also mentioning Newton's Law of Gravitation and big G).
Newton's Third Law of motion states that the force exerted by object A on object B is equal in size and opposite in direction, and of the same type, as the force exerted by object B on object A.
Newton's Second Law of motion states that the resultant force is proportional to the rate of change of momentum. F=ma is a special case where the mass is constant and there is a uniform acceleration.
Newton's First Law of motion states that if the resultant force on an object is zero then it will remain stationary or continue moving at a constant velocity.
