Answer:
a falling raindrop
Step-by-step explanation:
Kinetic energy depends on the mass and the velocity of an object.
Potential energy depends on the mass of an object an how high it is.
A raindrop initially has potenial energy because of its high above the ground, when is falling it has a velocity, and having a velocity means it now has kinetic energy.
By falling, the raindrop exchange potential energy for kinetic energy, as it falls, its potential energy is lower since it is at a lower altitud.
And also when it falls it accelerates towards the ground wich makes it have grater velocity and by analogy greater kinetic energy.
