Forms of Energy
Objective:
Can I recognize different types of
energy transformations?
What is the Law of Conservation of
Energy?
Forms of Energy
 Mechanical
 Thermal
 Chemical
Energy can be
transferred, or
converted, from
one form to
another!
 Electrical
 Electromagnetic
 Nuclear
Mechanical Energy
Energy associated with the motion of an
object.
Rest + Motion
Chewing
Sound
Frog Dancing
Thermal Energy
Heat Energy
All objects give off
thermal energy
Ice cream melting
gains thermal
energy
Chemical Energy
Potential energy stored in chemical
bonds.
Food
Fire Cracker
Stomach
Battery
Electrical Energy
Moving electrical charges that produce
electricity and energy.
Static Shock
Lightening
Computers/TVs/
Radios
Lights
Reality Check
Can I recognize different types of energy
transformations?
Electromagnetic Energy
Energy that travels in waves
Visible light
UV Rays
Microwaves
Electromagnetic Energy
Light Energy
Nuclear Power
Energy stored in the nucleus of an
atom from fission or fusion
Sun
Stars
Nuclear Power
Plant
Law of Conservation of Energy
Energy can NOT be created or destroyed,
only transformed from one form to
another.
With every energy transformation some
energy is always given off as heat energy.
