A ball is rolled on from the hill top with four labeled portion as P, Q, R, and S, which portion it will have its maximum kinetic energy.
At position P the ball has potential energy (energy that an object has due to its position). When it starts rolling down, the potential energy changes into kinetic energy (energy that an object has due to its movement) and at point S, it will have maximum kinetic energy as compared to points R and Q.
