A ball is projected vertically upward. If air resistance is ignored, which statement is correct?
- AThe kinetic energy of the ball is greatest at the greatest height attained.
- BBy the principle of conservation of energy, the total energy of the ball is constant throughout its motion.
- CBy the principle of conservation of momentum, the momentum of the ball is constant throughout its motion.
- DThe potential energy of the ball increases uniformly with time during its ascent.
