Standards S8P2. Students will be familiar
with the forms and transformations of energy.

• a. Explain energy transformation in terms of the
  Law of Conservation of Energy.
• b. Explain the relationship between potential and
  kinetic energy.
• c. Compare and contrast the different forms of
  energy (heat, light, electricity, mechanical
  motion, sound) and their characteristics.

Mechanical Energy
Throwing a baseball you have to subtract both
kinetic and potential energy and it can tell
about have far the ball will go.

• Mechanical energy is related to the position and
  motion of an object.
• Examples
• 1) Pitcher throwing a baseball
• 2) Throwing a football
• 3) Hammering a nail

When hammering a nail is mechanical energy
because you have to be precise. It can change
from mechanical to thermal energy because of the
friction of the hammer hitting the nail which
would also go to sound energy from when it hits
the nail.
when throwing a foot ball it has mechanical
energy because you have to add both potential and
kinetic energy to find the distance of how far
the ball will go.
4
Thermal Energy
An ice cream cone could both thermal and chemical
energy. It could be thermal once it begins to
melt in your mouth then change to chemical once
its in you feeding off energy to your body. Also
could be kinetic energy when the ice cream in
running down the cone while meting.

• The total of potential and kinetic energy of the
  particles in an object.
• Examples 1) ice cream melting
• 2) Lava going down a volcano
• 3) Boiling water

Boiling water is thermal because the pot you are
boiling the water in heats up for the water to
boil.
Lava going down a volcano is thermal because the
hot lava begins to loose its heat and harden.
5
Electric Energy

• Energy of electric charges. Can be either
  potential or kinetic depending on if they are in
  motion or being stored.
• Examples
• 1)Lightning
• 2)Getting shocked
• by doorknob 3)Power outlet

Lightning has electric charges that make it form
electric energy. This could also be thermal
energy if it stuck something because it can cause
heat. This is also be electromagnetic energy
because it causes light.
When getting shocked by a door knob it is
electric charges releasing to your hand.
A power outlet is an example of electric energy
because it gives off electricity to things that
are plugged into it.
6
Chemical Energy
Food is an example of chemical energy because it
gives energy to your body to do more things. This
could also be thermal depending on the food, or
when you are chewing from the friction. This
could be potential energy because before you eat
it is filled with energy.

• Bonds between the atoms and molecules hold a
  chemical compound.
• Examples
• 1) food
• 2) batteries
• 3) coal

A battery is a chemical energy because it is
chemical bonds getting ready to be released to
force something else to gain power.
Coal is a chemical energy because it is chemical
bonds getting ready to be heated to give off
energy (like a train).
7
Nuclear Energy

• Stored in the nucleus of an atom. His energy is
  released during a nuclear reaction.
• Examples
• 1) Power plants
• 2) Sun
• 3) Grenade

Power plants are nuclear because of the different
reactive things they give off into the air.
The sun is an example of nuclear energy because
the different charges it gives off to us on an
everyday base. It could also be light and thermal
energy. It could be light because it lights up
the world daily. It is thermal energy because it
gives off different amounts of heat depending on
where you are. But also it could be
electromagnetic energy because of the light
coming from it.
A grenade is nuclear because it can give off an
explosion or a very reactive affect.
8
Electromagnetic Energy

• Travels in waves, they have some electrical
  properties and some magnetic properties.
• Examples
• 1) X-rays
• 2) Radio
• 3) Microwaves

X-rays travel in light waves to figure the
different results of what it shows which is
electromagnetic.
Radio travel through waves such as sound waves.
A microwaves travel in several different
energies. It could go from electromagnetic from
the light, then could cause thermal energy from
the heat, but also sound energy because it comes
through with a sound.
9
Potential Energy

• The energy that is stored in an object.
• Examples
• 1) bike stopped on a hill
• 2) holding a ball before releasing it
• 3)pulling a bow string back

When the bike is at the top of the hill it has
the highest point of potential energy because it
is soon going to be transferred to kinetic.
A bow is an example because when you pull it back
it is filled with potential energy to be released
into kinetic. This could also be thermal energy
once it hits what you are aiming for when it rubs
together to make heat. But also could be
mechanical because you should have a precise
motion.
Before pitching the ball you have a full amount
of potential because you are about to let go with
all of your power to the ball.
10
Kinetic Energy

• Kinetic energy is the energy being released from
  an object
• Examples
• 1) Throwing a ball
• 2) riding a bike down a mountain
• 3) Using a battery

When a pitcher throws a ball it is giving
transferring from potential to kinetic while in
mothing.
Riding a bike down a hill is an example of
kinetic because it is giving off potential and
changing to kinetic. This is also thermal energy
depending on what the ground is like you are
riding on. But also sound if you can hear you hit
different rocks or the tires/metals making noises.
Using your phone means you are using your battery
which means you are giving off potential to
kinetic from the highest and lowest point to
kinetic energy. You are using up kinetic that
will soon be potential when it dies.
11
Sound Energy

• Sound energy is the different noises you hear.
• Examples
• 1) vacuum
• 2) blow dryer
• 3) coke/ soft
• drinks

A vacuum starts at electrical energy from when
you plug it in then goes to sound and then goes
to thermal from he friction from moving it around
on the floor.
A blow dryer is an example of sound because when
you use it, it has a sound.
Coke is an example of sound because when you open
it, it has a fizz/ bubble sound.
12
Law of Conservation of Energy
For example if you have potential standing in one
place then you began to walk it will began to
change into kinetic with motion.

• Energy may not be lost/destroyed nor be
  gained/made

Energy can never be taken away. It can only be
transferred from one type to another.
