Astone held above the ground has potential energy. when the stone is dropped, potential energy is converted to energy.
a. chemical
b. thermal
c. electrical
d. kinetic

The answer is (D) kinetic. Potential energy is the energy that is stored in an object relevant to its vertical position. When you are holding a rock up high, it has its potential energy stored within it. Kinetic energy is the energy that the object has due to its motion, or the amount of work required to get an object from a point of rest to the point of its current velocity.

The awnser is b i believe

That would be a working theory.
