2. Make Up of Energy
Energy is all around you!
You hear energy as sound, you see energy as
light, you can feel energy in wind
Living organisms need energy for growth and
movement.
You use energy when you kick a ball, catch a ball,
or even lift a grocery bag.
THEREFOR: ENERGY IS THE ABILITY TO DO
WORK.
3. Other Forms of Energy
5 main forms of
energy:
Mechanical Energy
Heat Energy
Chemical Energy
Electrical Energy
Gravitational Energy
4. Mechanical Energy
Mechanical Examples:
Energy: is the Water in a waterfall
energy of motion Wind
that does the work.
Moving Vehicles
Sound
5. Heat Energy
Heat energy: is Examples:
energy that is Friction
pushed into motion Sun (also known as
by using heat. thermal energy)
Radiation
Fire
6. Chemical Energy
Chemical Examples:
Energy: is energy Digesting food,
caused by chemical bonds are broken to
reactions. A good release energy for
example of chemical the body to store
energy is food when and use
it is cooked. Photosynthesis
Using energy to play
sports
7. Electrical Energy
Electrical Examples:
Energy: is when Power lines carry
electricity creates electricity
motion, light or heat. Electrical motors
Light (X-rays, radio
waves, laser light
etc.)
Lightning
8. Gravitational Energy
Gravitational Examples:
Energy: is motion Water that is pulled
that is caused by down a waterfall
gravity. The pull felt when
you jump up that
forces you to come
back down.
9. Learning Goals
What is energy?
Can energy be transferred from one
object to another?
What are the different forms of energy?
11. Potential Energy
Potential Energy: is stored energy.
Examples of potential energy are oil
sitting in a barrel, or water in a lake in
the mountains. This energy is referred to
as potential energy, because if it were
released, it would do a lot of work.
12. Kinetic Energy
Kinetic Energy: is energy that is in
motion. Moving water and wind are good
examples of kinetic energy. Electricity is
also kinetic energy because even
though you can't see it happen,
electricity involves electrons moving
in conductors.
13. The Lighter Side of Energy
What would a barefooted man get if he
steps on an electric wire?
(Answer) A pair of shocks.
Wind power is very popular because it
has a lot of fans.
What would you call a power failure?
(Answer) A current event.
What's the best way to charge a car
battery?
(Answer) With a credit card.
14. Assignment!!!
