A ball is projected into the air from horizontal ground and follows the path shown in the diagram. [Figure showing a projectile path with points Q, R, S, T and their heights] At points Q, R, S and T, the ball has kinetic energies EQ, ER, Es and ET respectively. The heights above the ground of these four points are shown. Air resistance is negligible. Which difference in kinetic energies is the smallest?
