Facts of Energy
This picture show the change of
potential and kinetic energy.
● Energy isn’t destroyed or created.
● Kinetic energy is measured in joules .
Forms of Energy continued
● Energy-the ability to do work
● Energy has many different forms
● Energy can only be transformed, it can’t be created or
destroyed.
This light shows
types of energy.
Forms of Energy continued
●
Kinetic energy- the energy of motion
● An object keeps the same amount of kinetic energy
unless it speeds up or slows down.
This ball shows
motion so its
kinetic energy.
Forms of Energy continued
● Mechanical Energy- the total of
potential and kinetic energy in an object.
● The Law of Conservation of Mechanical Energy says
that an object’s mechanical energy remains constant
under normal circumstances
At the top of the
hill, the car has
potential
energy.
Forms of Energy continued
● Thermal energy- energy a substance
thats related to temperature.
● Its temperature and heat.
This shows
thermal energy
because there
is heat and
temp.
Forms of energy continued
● Chemical energy- is the energy stored in chemical
bonds.
● Chemical energy is stored inside a substance or object
until it is involved in a chemical reaction.
A battery is an
example of a
chemical
energy.
Forms of energy continued
● Electrical energy- is the energy associated with
electric charges.
Lightning is an
example of
Electrical
energy.
Forms of energy continued
● Electromagnetic energy- is a form of energy
through space.
heat from the
sun is an
example of a
Electromagnetic
energy.
Forms of energy continued
● Nuclear energy- is the energy stored in
atomic nuclei.
power plants is an
example of Nuclear
energy.
Forms of energy continued
● Energy conversion- the process of changing
energy from one form to another.
Any energy can
convert to another
energy.
Forms of energy continued
● Nonrenewable- exist in limited quantities
and, once used, cannot be replaced except
over the course of million of years ago.
There’s some
examples of
Nonrenewable
energy resources.
Forms of energy continued
● Fossil Fuels- rich deposits of hydrocarbon
mixture that formed from the remains of
organisms.
These are some
examples of
Fossil fuels.
Forms of energy continued
● Renewable energy- resources that can be
replaced in a relatively short period of
time.
Here are some
examples of
Renewable
resources.
Forms of energy continued
● Hydrogen fuel cell- generated electricity by
reacting hydrogen with oxygen.
An example of
producing
electricity.
Forms of energy continued
● Energy conservation- finding ways to use
less energy to use energy more efficiently.
Examples of
energy saving
solutions.
