What is Energy?
Energy is the ability to
A. Do Work
B. Cause Change
C. Speed
D. Accelerate
Two Types of Energy Are:
Potential Energy
•The energy an object
has because of where it
is or its shape.
Kinetic Energy
•The energy of motion.
Forms of Energy
Light
Heat
Electric
Sound
Atomic
Chemical
Mechanical
Heat Energy
• A form of energy whose source
is the motion of molecules.
When something is heated, the
atoms or molecules in it begin
to move faster. The hotter an
object is, the quicker its
molecules are moving.
Heat can travel in 3 ways!
Light Energy
• Light is electromagnetic
energy. It can travel
through air and other
transparent substances,
and through empty space.
Light travels at the fastest
speed ever measured:
186,000 miles per second.
Sound Energy
• All sounds are made by
something vibrating rapidly
back and forth. Sound
travels through air at a
speed of 750 miles per
hour.
Electrical Energy
Mechanical Energy
• This is the energy of
motion. The wind, cars
moving, riding a bike, and
even sound are all
examples of mechanical
energy.
Chemical Energy
Nuclear/Atomic
Energy
• This is the energy found
inside the atom. The sun
carries on a nuclear
reaction all the time
releasing amounts of
energy. Nuclear power
plants generate electricity.
