What is Potential Energy?
o Energy that is stored
and waiting to be
used later
What is Gravitational Potential
Energy?
o Potential energy
due to an object’s
position
Don’t look down,
Rover!
Good boy!
o P.E. = mass x
height x gravity
What is Elastic Potential Energy?
o Potential energy due compression or
expansion of an elastic object.
Notice the ball compressing
and expanding
What is Chemical Potential Energy?
o Potential energy
stored within the
chemical bonds of
an object
What is Kinetic Energy?
o Energy an object has due
to its motion
o K.E. = .5(mass x speed2)
What is thermal energy?
Thermal energy is the energy an object
has due to its temperature.
What is light energy?
Energy carried by light, called radiant
energy
What is electrical energy?
Energy carried by an electric current
What is nuclear energy?
The energy contained in the nucleus of
atoms
