- A conservative force is one where, given a
- force, an origin, and an ending point, the work needed
- to move an object from the origin to the ending point is
- independent of the choice of path. Another way of
- considering conservative forces is that if an object
- completes a round trip, leaving from a given point and
- eventually returning to the same point, the total work
- done must be 0.
- Conservative forces have associated potential energy
- definitions. An example of a conservative force is the
- force due to gravity. An example of a non-conservative
- force is a force due to friction. In the case of friction, an
- object may lose kinetic energy that is not converted to
- potential energy. Such energy may be lost as heat in the
- friction between the surfaces.
