A ball is thrown vertically upwards into the air. It rises to the top of its path before beginning to fall vertically downwards. [Figure 16.1] Assume that the gravitational potential energy of the ball is zero at its starting position. Which statement about the ball is not correct?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
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.
✓ Correct answer
B: At the midpoint of its path, its gravitational potential energy is equal to its initial kinetic energy.
