Question

A stone 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

Answer 1

Kinetic

Step-by-step explanation:

When a stone is held above the ground, its position gives it potential, or stored, energy. When the stone is dropped, the potential energy is converted to kinetic energy, or the energy of motion.

This is an example of the law of conservation of energy, which states that energy cannot be created or destroyed. It can, however, be converted from one form to another.

Answer 2

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.
