Problem
A ball of mass m is thrown straight upward and moves only under the influence of gravity (air resistance is negligible).
(1) If the system is taken to be the ball alone, is the mechanical energy of that system conserved while the ball rises? Explain briefly.
(2) If the system is taken to be the ball plus Earth, is the mechanical energy of that system conserved while the ball rises? Explain briefly.
