Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

In most of the problems you have dealt with so far, weight is equal in magnitude to that of the normal force. Is it possible for the normal force not to be equal to weight? Explain your answer. Yes, it is possible. Oftentimes, normal force counteracts the weight, thus making them equal. This happens when the object is situated on a horizontal surface and the force is exerted on the direction of the gravitational field. Otherwise, as in the case of an elevator accelerating downwards, N and W will not equalize. Yes, it is possible. Oftentimes, normal force counteracts the weight, thus making them equal. This happens when the object is situated on a vertical surface and the force is exerted on the direction of the gravitational field.
