Potential Energy
• Potential Energy- is energy that is stored
in an object.
– It is due to the object’s position or to
substances the object is made of.
– Example: A diver standing on the diving board
has potential energy because she is above
Earth’s surface and will fall due to the force of
Earth’s gravity.

Kinetic Energy
• Energy that an object has because it is
moving is kinetic energy.
• Energy often changes back and forth
between potential and kinetic energy.
