Answer 2

The above activity demonstrates the "Law of Conservation of energy"

As balls roll down, the value of 'h' decreases due to which P.E also decreases as P.E= mgh. At the same time, the velocity of the balls increases as they roll down due to which their K.E increases as K.E= ½ mv²

Thus, we find that P.E decreases while K.E increases. But energy can neither be created nor destroyed. Thus, the P.E that decrease is in fact being converted to K.E.
