Potential and Kinetic Energy
Captions available
The idea
Potential energy comes from an object's position, composition, or condition; kinetic energy comes from its motion.
In practice
Water held behind a dam has potential energy that converts to kinetic energy as it falls and spins the turbines below.
Where people slip
A substance's stored chemical energy counts as potential energy even while the substance itself sits perfectly still on a shelf.
