Download Types of Energy

Forms of Energy
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 Energy
Sometimes 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

• 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.

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.
