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.

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.
