查到了哈!in every interaction,there is a pair of forces acting on the two interacting objects.The size of the force on the first object equals the size of the force on the second object.The direction of the force on the first object is opposite to the direction of the force on the second object.Forces always come in pairs - equal and opposite action-reaction force pairs.
