Energy Transformations: Notes are HIGHLIGHTED

Like matter, energy cannot be created or destroyed.

Energy can be transferred, or passed, from one
object to another.

Multiple Choice

When energy is released, it disappears.

• True

• False

Energy can be transformed, or changed into a
different form of energy.

Energy transFer

When you ride a bicycle, mechanical
energy from your body is transferred
from you to the pedals to make the
bike move.

When you charge your cell phone,
electrical energy is transferred through
the cord from the outlet to your phone.

An energy transformation

occurs when one form of energy

is converted or changed into

another.

via

● Kinetic energy is the

energy of motion, and
potential energy is stored
energy. Either of these
can transform into the
other.

​Energy Transformations:

Kinetic and Potential

Roller Coaster Physics

Multiple Choice

• W

• X

• Y

• Z

Multiple Select

Which of following are types of kinetic energy? Check all that apply.

• sound energy

• light energy

• thermal energy

• mechanical energy

• potential

Plants take radiant energy and changes into food
(chemical energy).

A car engine changes chemical energy stored in the
fuel gasoline into mechanical energy that moves the
car.

A light bulb changes electrical energy into
light and heat, which are forms of radiant
energy.

A flashlight changes chemical energy stored in
batteries into electrical energy, then into light
energy.

The food you eat breaks down and releases chemical
energy that your body converts into mechanical energy
so you can move and do activities.

A toaster oven converts electrical energy into heat
energy.
