Without the force of gravity though, what will the potential energy equation look like? Will there even be a potential energy equation or would it just be the change in energy, W = Fd?
Homework Statement
A particle of mass m rests atop a frictionless hemisphere of radius R. A force F = -mkyα acts in the y direction. After an initial small displacement, the particle slides down the sphere under the action of the force.
