What is Energy ? • Energy is the capacity to

preform WORK.

• Work is transferring energy from one thing to another.

Example: Kicking a ball

What is Work ?


Kinetic Energy • All moving things have kinetic energy. • The heavier something is the more kinetic

energy it has.

Example: Running Track and Field


Potential Energy• Potential energy is the stored energy

possessed by an object.

Example: Pulling back a bow string

Mechanical Energy

• Mechanical Energy is the combination of kinetic and potential energy in an object.

Example: Swinging a hammer to hit an object such as a nail.


Sound Energy• Sound is the movement of energy

through substances in waves.

• Sound is produced when a force causes an object or substance to move.

Example: Your alarm clock or playing the drums


Thermal Energy• Thermal energy comes from the temperature

of and object.

• The warmer the substance is the more energy it has.

Example: the sun


Chemical Energy• Chemical energy is energy stored in the

bonds of atoms and molecules.

Example: breaking down food in our stomachs to give us energy


Electrical Energy• Electrical Energy is generated by the

movement of electrons, electrons are inside an atom.

Example: Any object that plugs into the wall.


Gravitational Energy

• Gravitational energy is the amount of force exerted on an object or substance by the gravitational pull of the Earth.

Example: Sky Diving


Radiant Energy• Radiant energy is the energy of

electromagnetic waves.• The shorter the wavelength, the higher the

energy level.• It is the only form of energy that can travel

through space.

Example: Using a flashlight or a lightbulb


Electricity


What do the red areas represent? • Areas that use a lot of electricity.

What do the blue areas represent ? • Areas that do not use a lot of electricity.

What is Electricity Used for? • Heating, cooling, cooking, appliances.

Do you see any shapes/patterns? • Look closely and you can see certain

patterns such as streets and subdivisions (groups of houses).
