Questions based on paragraph Study the following activity and answer the questions. Take two aluminium channels of different lengths. Place the lower ends of the channels on the floor and hold their upper ends at the same height. Now take two balls of the same size and weight and release them from the top end of the channels. They will roll down and cover the same distance. What is the form of the eventual total energy of the balls?
