Momentum:

$\overline{){\mathbf{P}}{\mathbf{=}}{\mathbf{m}}{\mathbf{v}}}$

Kinetic energy:

$\overline{){\mathbf{K}}{\mathbf{E}}{\mathbf{=}}\frac{\mathbf{1}}{\mathbf{2}\mathbf{}}{\mathbf{m}}{{\mathbf{v}}}^{{\mathbf{2}}}}$

Potential energy:

$\overline{){\mathbf{U}}{\mathbf{=}}{\mathbf{m}}{\mathbf{g}}{\mathbf{h}}}$

The velocity of the ball decreases as it goes up. Consequently, kinetic energy and momentum of the ball decrease. Hence, the kinetic energy and momentum are not conserved.

The height of the ball increases. Aa a result, the potential energy of the ball increases as it goes up.

A baseball is thrown vertically upward and feels no air resistance. As it is rising:

A) Its kinetic energy is conserved, but its momentum is not conserved.

B) Both its momentum and its kinetic energy are conserved.

C) Its momentum is not conserved, but its mechanical energy is conserved.

D) Both its momentum and its mechanical energy are conserved.

E) Its gravitational potential energy is not conserved, but its momentum is conserved.
