The body was thrown from a certain height vertically downward. How does acceleration, potential energy

The body was thrown from a certain height vertically downward. How does acceleration, potential energy, total energy of the body change in this case?

Since the direction of motion of the body coincides with the direction of the silt of gravity, the initial velocity will always be lower than the final velocity of the body. This is due to the constant effect of the acceleration of gravity on it.

Acceleration is constant throughout the entire height:
a = g = const.

Potential energy according to the formula Ep = mgh is equal to the value of the height at which the body is located.
When falling down, the body will lose height, respectively, the potential energy will decrease.

The total energy of the body throughout the entire height will remain unchanged, since the sum of the kinetic and potential energy is unchanged:
Etot = Ekin + Epot = const.

Answer: Acceleration will not change, potential energy will decrease, total energy will not change.
