Determine whether kinetic energy is being converted to potential energy, or vice versa, in the following processes. A) Water cascades downward in a waterfall.
B) A player kicks a football.
C) An electric current is generated by a chemical reaction in a battery.
D) Water boils when heated on a gas stove.

All the processes given involves the conversion of potential energy to kinetic energy

Explanation:

The kinetic energy is the energy possessed by an object because of its motion, equal to one half the body's mass times the square of its speed.

i.e

On the other hand, The potential energy is the energy possessed by an object because of its position in a gravitational or electric field, or its condition as a stretched or compressed spring, as a chemical reactant,or by having rest mass.

SO, from both definitions :

Water cascades downward in a waterfall → involves the conversion of potential energy to kinetic energy

A player kicks a football  → involves the conversion of potential energy to kinetic energy

An electric current is generated by a chemical reaction in a battery.  → involves the conversion of potential energy to kinetic energy

Water boils when heated on a gas stove.    → involves the conversion of potential energy to kinetic energy

ill try to . no promises tho.
