Mechanical Energy
 Mechanical energy is the energy of motion and position of an object.
 Also known as muscle or motor energy
 Both kinetic energy and potential energy are kinds of mechanical
energy.
Examples:
Fan blades
Turbines (big mechanical fans)
Throwing a football
Riding a bike
Wind
Bus driving
Frog leaping
Thermal Energy
 THERMAL ENERGY is the rapid movement of atoms and molecules.
 Also Known As: HEAT
 It is all of the kinetic energy (movement) of the atoms and molecules that
make up substances.
 Everything has atoms, so everything has thermal energy (heat)
Examples:
Fire
Heaters
Sun
Light bulbs
People
Electrical Energy
• Electrical Energy is the energy stored in electrons(electricity)
• Electrical energy can be thought of as potential energy that is waiting to be
used. The potential energy is changed into kinetic energy when you plug in
an electrical appliance and use it.
Examples:
Lightning
Electricity
TV
Cell phones
Batteries
Radios
Flashlights
Chemical Energy
CHEMICAL ENERGY is the energy stored in the bonds of chemical
compounds
When bonds break the energy is released
Examples:
Food
Plants
Oil and Gasoline
Match tip
Batteries
Coal
Nuclear Energy
NUCLEAR ENERGY is the energy stored in the nucleus(center) of
an atom
• Nuclear energy can be produced when nuclei are joined in a
fusion reaction or when a nucleus is split apart in a fission
reaction.
Examples:
Uranium
Nuclear power plants
Nuclear bombs
Sun
Light Energy
(aka electromagnetic)
Light Energy is energy in the form of moving rays that produce
light
Examples:
Light bulbs
Sun
Head lights
Flashlights
Candles
Sound Energy
Sound Energy is caused by an object’s vibrations to make noise
 The object’s vibrations transmit some kinetic energy to the air
particles, which also vibrate. These vibrations cause sounds.
Examples:
Drums
Talking
Radio
Engines
Maracas
Tuning fork
