DESCRIPTION
Kinetic Energy Energy of motionTRANSCRIPT
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!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.
