- ABy the principle of conservation of energy, the total energy of the ball is constant throughout its motion.
- BBy the principle of conservation of momentum, the momentum of the ball is constant throughout its motion.
- CThe kinetic energy of the ball is greatest at the greatest height attained.
- DThe potential energy of the ball increases at a constant rate during its ascent.
