Additional information: Conservative force: A conservative force is a force with the property that is independent of the way the total function in moving a particle between two points. WebIn physics, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled.
