Energy: the ability to cause
changes in matter
Energy can be transform, or
change,
from one form into another.
Example:

A child kicks a ball.

The child has
energy
from food

Ball gets
energy from
foot

Ground and air
absorb energy
...
Can anyone
think of another
example of how
energy can
change forms?
In your groups, answer the
following question:
Does a ball have energy when it is
just sitting on the table? Why or
why no...
Yes, because
someone gave it
energy when they put
it on the table.
This is called
potential energy.
Potential Energy
The energy of an object
that is because of it's
condition or position.
Can be thought of as
stored energy...
Potential Energy changes to
kinetic energy!
c Energy
nergy an object has because it is in mo
Forms of Energy
- Sound - Electrical
- Thermal- Mechanical
- Light

- Chemical
Sound Energy
A type of kinetic energy
because air or
particles are in motion.
Thermal Energy
The tiny particles that make
up matter are in motion,
causing kinetic energy.
Light Energy
You can see energy
when light comes off an
object and hits your
eyes.
Electrical Energy
Energy that caused by
movement of electrical
charges, or electricity.
Mechanical Energy
Potential Energy + Kinetic
Energy = Mechanical
Chemical Energy
Energy that is released
from a chemical reaction.
Law of Conservation of Energy
Energy does not appear or
disappear.
It only changes forms.
Energy cannot be created or
dest...
Examples:
Flashlight: Batteries create chemical
energy which causes it to emit light and
heat energy.
Radio: Uses electric...

Introduction Energy

  1. 1. Energy: the ability to cause changes in matter Energy can be transform, or change, from one form into another.
  2. 2. Example: A child kicks a ball. The child has energy from food Ball gets energy from foot Ground and air absorb energy from ball When all energy is used up the motion stops
  3. 3. Can anyone think of another example of how energy can change forms?
  4. 4. In your groups, answer the following question: Does a ball have energy when it is just sitting on the table? Why or why not?
  5. 5. Yes, because someone gave it energy when they put it on the table. This is called potential energy.
