A massless rope to which a force can be applied parallel to the surface is attached to the crate and leads to the top of the incline. This is the principal mode of operation of roller coasters (without any propulsion systems installed in the cars) which allows them to negotiate a series of slopes and hills without running out of energy. Describe this process in more detail, in particular, explaining how it is related to the fact that kinetic friction is less than static friction. Wnc is any work done by non-conservative forces, such as friction or a push, which take energy in or out of the system of interest.

If a car takes a banked curve at less than the ideal speed, friction is needed to keep it from sliding toward the inside of the curve (a problem on icy mountain roads). Including Wnc in some form is more general and gives an equation that is true in all situations, including those with non-conservative forces such as the second question in this problem. Suppose a mass is moving in a circular path on a frictionless table as shown below. and others use U. All that matters for describing motion and energy is that you explicitly state where your reference point is. (a) At point A.
