WebFigure 7.3 Work done by a constant force. (a) A person pushes a lawn mower with a constant force. The component of the force parallel to the displacement is the work done, as shown in the equation in the figure. (b) A person holds a briefcase. No work is done because the displacement is zero. WebApr 23, 2024 · Updated on April 23, 2024. In physics, work is defined as a force causing the movement—or displacement—of an object. In the case of a constant force, work is the …
