... Work and Gravitational Potential Energy (GPE) • If I lift an object, I do work (F x d), and this work is stored as PE. The work done when I lift a mass m up a distance h is, W = F d = (mg) h = mgh • The PE that an object gets when it is lifted by an amount h is called Gravitational Potential Energy ...
