What is the kinetic energy of particle moving in a equipotential surface?
Whether is it constant or variable?

hi saravanan13! :smile:

you mean, like a pooltable?

KE + PE = constant, so if the potential energy is constant then the kinetic energy must be constant also

(though if it's not constrained to stay on the equipotential surface, and if that surface is curved, it will probably move off it :wink:)
