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
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.
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 examples.
