WebA point force is a force that acts at a single point. Examples would be the push you give to open a door, the thrust of a rocket engine, or the pull of the chain suspending a wrecking ball. In reality, point forces are an idealization as all forces are distributed over some amount of area. Point forces are also called concentrated forces. WebFor example, a swimmer pushing off a pool wall (the action) exerts a force on the wall, and the wall also exerts a force (the reaction) on her. To figure out if she accelerates, we only consider the forces on her and then apply Newton’s second law. See the “How-to identify action-reaction pairs” section above for more details.
