Mechanical Energy
Mechanical energy is energy associated
with the POSTION and MOTION.
Mechanical energy is a COMBINATION of
the objects potential and kinetic energy.
Mechanical energy = potential energy + kinetic energy
See pg. 448
Other Forms of Energy
Forms of energy associated with the
PARTICLES of objects.
Too small to see
Thermal Energy
Thermal energy is the total potential and
kinetic energy of the PARTICLES in an
Ice cream
Electrical Energy
Electrical energy is the energy of electric
Electrical lines
Chemical Energy
Chemical energy is the potential energy
stored in the chemical bonds that hold
chemical compounds together.
Cells of your body
Nuclear Energy
Nuclear energy is potential energy stored in the
nucleus of an atom and is released in a nuclear
Nuclear fission – when a nucleus splits
used by nuclear power plants to produce electricity.
Nuclear fusion – when nuclei of atoms fuse or join
Occur continuously in the sun, releasing tremendous
amounts of energy.

Electromagnetic Energy
Travels in waves
Have some electrical properties and some
magnetic properties.
Sunlight is a form of this wave.
Microwaves, ultraviolet radiation, infrared
radiation, and radio waves are also
