What's the difference between kinetic and potential energy?

• Potential energy is in the ground; kinetic energy is in the air.

• Potential energy isn't real; kinetic energy is real.

• Potential energy isn't in motion; kinetic energy is in motion.

• Potential energy is red on a graph; kinetic energy is blue on a graph.
