A ball is projected straight up into the air. It reaches the highest point of its motion and then starts to move straight downwards. Assume that the ball’s gravitational potential energy is zero at the point where it starts. Which statement about the ball is not correct?
- AAs it rises, its kinetic energy is transferred to gravitational potential energy.
- BAt the midpoint of its path, its gravitational potential energy is equal to its initial kinetic energy.
- CAt the top of its path, its kinetic energy is zero.
- DAt the top of its path, its total energy is less than its initial total energy.
