2 Lecture 14, 3/1/00 Phy1221 Winter 00 3 Gravitational Potential Energy Note that we did not have to know anything about the shape of the upper part of the ramp to determine the height required: A conservative force is one with this property: the work done by the force does not depend on the path. Such forces can have an associated potential energy defined. ( conservative: gravity, electrostatic force, spring force…, nonconservative: friction, drag, …) Change in gravitational potential energy
