Using the energy conservation, derive the expressions for the minimum speeds at different locations along a vertical circular motion controlled by gravity. Is zero speed possible at the uppermost point? Under what conditions? Also prove that the difference between the extreme tensions (or normal forces) depends only upon the weight of the object.
