Conservation of Energy: The Inclined Plane Background: In the absence of friction, the work done to pull an object up an incline plane is equal to the work done to lift the object up the same vertical distance. That is, the change in gravitational potential energy is independent of the path taken to get to the height. When lifting an object straight up, work is only done against gravity. The work done by the moving force is equal to the change in gravitational potential energy if the object
