What is Energy ? • Energy is the capacity to
preform WORK.
• Work is transferring energy from one thing to another.
Example: Kicking a ball

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
