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
object.


Lava
Ice cream
Electrical Energy

Electrical energy is the energy of electric
charges.


Lightning
Batteries
Electrical lines
Chemical Energy

Chemical energy is the potential energy
stored in the chemical bonds that hold
chemical compounds together.


Food
Matches
Cells of your body
Nuclear Energy

Nuclear energy is potential energy stored in the
nucleus of an atom and is released in a nuclear
reaction.

Nuclear fission – when a nucleus splits


used by nuclear power plants to produce electricity.
Nuclear fusion – when nuclei of atoms fuse or join
together.

Occur continuously in the sun, releasing tremendous
amounts of 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
examples.
