Unit 8 Review

Electrical energy is the energy caused by the movement of electrons. It powers devices like lights, computers, and appliances.

Mechanical energy is the energy that an object has due to its motion (kinetic energy) or its position (potential energy).

A remote-controlled car uses electrical energy from its battery to produce mechanical energy, allowing it to move.

A computer monitor transforms electrical energy into light energy and heat energy.

A solar panel converts light energy from the sun into electrical energy that can power appliances.

Wind power is energy generated from the wind, which turns turbines to convert mechanical energy into electrical energy.

When a phone rings, electrical energy is transformed into sound energy.

Energy transformations occur when energy changes from one form to another, such as electrical energy to mechanical energy.

Using wind power to generate electricity is an example of energy conservation, as it reduces reliance on fossil fuels.

Light energy is a form of energy that is visible to the human eye and is produced by sources like the sun and light bulbs.
