Remember…all forms of energy are either kinetic

or potential

Kinetic Energy• Energy of motion

Potential• Stored energy • Positional energy– PE=heightXmassXgravity

Thermal Energy• Definition: Heat. Vibration and movement of

the particles in a substance• Examples: geothermal, sun, fire• **Friction produces heat nrg

Motion EnergySometimes called Mechanical Energy

• Definition: Movement of objects and substances from one place to another.

• Examples: wind (air particles), transportation

Gravitational Energy• Definition: Energy due to objects height

above the earth’s surface. – Mass & height determine amount of PE

• Examples: marble top of ramp, water behind hydropower

Stored Mechanical Energy• Definition: Energy stored in objects by

applying force (push or pull).

• Examples: compressed springs and stretched rubber bands

Radiant (Light) Energy• Definition: Electromagnetic energy that travels in

transverse waves

• Examples: light, X rays, radio waves, sun

Chemical Energy• Definition: Energy stored in the bonds of

molecules. The energy that holds the particles together.

• Examples: biomass (wood), fossil fuels (oil), batteries, living organisms-plants/animals

Electrical Energy• Definition: The movement of electrons,

usually thru a wire.

• Examples:• lightning • Any electric appliances

Sound Energy• Definition: Movement of energy through

waves; vibration of air particles.

• Examples: music, speaking, noise, tree falling in forest…

Nuclear Energy• Definition: Energy stored in the nucleus of an

atom• Example:

• fission-nuclear power plants, bombs • fusion-energy produced in sun

Exit Ticket• First and last name• Draw the lab set up on page 2 or 3: marble,

ramp, ½ cup• Label as many forms of energy as you can.

Point to exactly where they are in your picture.

QUIZ TIME!What type of energy cooks food in a microwave oven?

ELECTROMAGNETIC ENERGY

What type of energy is the spinning plate inside of a microwave oven?MECHANICAL ENERGY

QUIZ TIME!Electrical energy is transported to your house through power lines.When you plug an electric fan to a power outlet, electrical energy is transform into what type of energy?

MECHANICAL ENERGY

O.A. 2/15Categorize Forms NRG into

TYPES of NRG• Sort the forms of energy into the two TYPES of

energy: Kinetic or Potential: • electrical, sound, gravitational, nuclear,

chemical, motion, thermal, radiant, mechanical, elastic, etc.
