• All forms of energy fall under 2 categories:

Potential

Kinetic

• This is stored energy that is capable of producing motion.

• This is also energy that gravity works on.

Potential Energy

Potential• Chemical • Nuclear• Stored Mechanical• Gravitational

Eureka Potential

“Good Canoes Never Sink”

Chemical Energy• Energy stored in the

bonds of atoms and molecules.– Examples- • Petroleum

(gasoline) • Natural gas• Batteries• Food

Nuclear Energy

• Energy that is stored in the nucleus of an atom

• Energy that holds the nucleus together.

Stored Mechanical Energy

• Energy that is stored in objects by application of a force.

• Example-–Compressed

springs– Stretched rubber bands

Gravitational Energy• Energy of place or

position.–When I hold a ball in

the air - if I let it drop gravity will act on it

• When the ball is let go it becomes an example of

motion energy

Kinetic Energy

• This is energy in motion.

• Kinetic energy is the motion of : –Substances–Electrons–Waves

Kinetic• Thermal• Electrical• Radiant• Motion • Sound

Eureka Kinetic

“TERMS”

Thermal Energy• HEAT• Internal energy in

substances.• Vibration and

movement of atoms and molecules within substances–Geothermal

energy

Electrical Energy• Is the movement of

electrons.– Lightning – Electricity

Radiant Energy• Electromagnetic

energy that travels in transverse (up and down) waves.

• This energy includes:– Visible light– X-rays– Gamma rays– Radio waves

Motion

• Movement of objects or substances from one place to another.–Wind–Hydropower

Sound

• Movement of energy through objects in longitudinal

waves.
