2. What is Energy?
• Energy is the ability to do work.
• There are two main types of energy:
• Potential
• Kinetic
3. Potential Energy
• Energy that is stored and being held,
waiting to be used is potential
energy.
• Examples:
• A car parked in a parking lot
• A child at the top of a slide
• A ball sitting on a table
• Someone pulling a arrow back on a bow
4. Kinetic Energy
• The energy of motion is kinetic
energy.
• Examples:
• Rolling a ball down a hill
• Going down a hill on a roller coaster
• Riding your bicycle
8. What is
Mechanical
Energy?
o Energy due to a
object’s motion (kinetic)
or position (potential).
The gears in a watch
have mechanical
energy.
When the gears turn it
moves the arms of the
watch.
10. What is
Electrical Energy?
o Energy caused by
the movement of
electrons
o Easily transported
through power lines
and converted into
other forms of energy
12. What is Chemical
Energy?
o Energy that is
available for release
from chemical
reactions.
The chemical bonds in
a matchstick store
energy that is
transformed into
thermal energy when
the match is struck.
14. What is Thermal
Energy?
o Heat energy
o The heat energy of an
object determines how
active its atoms are.
A hot object is one whose atoms
and molecules are excited and
show rapid movement.
A cooler object's molecules and
atoms will show less movement.
16. What is Sound
Energy?
Sound is the movement of
energy through substances in
waves.
Sound is produced when a
force causes an object or
substance to vibrate.
