Jan 11, 2015 at 21:38 comment added Admin Voter So saying that just the object itself follows the conservation of energy would be wrong? Because it is neglecting that the energy was taken away from the object and into the air around it, correct?
Jan 11, 2015 at 21:30 comment added Sofia @AdminVoter : yes, the paragraph wanted to say that not all the potential energy goes to the increasing of the ball's kinetic energy. In fact part of the kinetic energy is stolen by the surrounding air molecules through friction.
