Webphysics, science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe. In the broadest sense, physics … WebSince there are 2 types of forces being exerted on the body (Weight force, Push force), to have a vertical net force = 0N; there would also be a force acting vertically-upwards that can cancel out these 2 forces. That force is the Normal force (Support force) and to cancel out, the Normal force = Weight force + Push force.
