Work (physics)

In science, 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. A force is said to do positive work if it has a component in the direction of the displacement of the point of application.

A force does negative work if it has a component opposite to the direction of the displacement at the point of application of the force.
