• Energy
• Potential energy
Gravitational potential
energy
Kinetic energy
• The ability to do work.
• Energy stored based
on position or
chemical composition.
• Weight X height
• Energy of motion.
• Depends on the mass
& velocity of the
moving object.
• Forms of energy

Nuclear
Sound
• Light
• Heat/Thermal
• Produced by the
vibrations of electrically
charged particles.
• Transfers energy without
a medium.
• All of the kinetic energy
due to random motion of
the particles.
• Depends on the number
of particles as well as the
temperature .
• Chemical
• Electrical
• The energy of a
compound that
changes as its atoms
are rearranged.
• A form of potential
energy.
• The energy of moving
electrons.
• Mechanical
• Total energy of motion &
position of an object.
• ME=potential + kinetic
• Nuclear
• Energy that comes from
changes in the nucleus of
an atom.
• Fission-splitting of an
atom. (Power plants)
• Fusion-joining of nuclei to
make a larger nucleus.
(Sunlight & heat)
• Sound
• Energy Transformations
• A vibrating object
transmits energy through
the air around it.
• Travels as a longitudinal
wave.
• Energy can be
transformed from one
type to another.
• Some of the energy is
lost to the environment as
heat.
