Pg 81 #4

Electrical energy is transmitted through wires, and then converted into many other forms of energy.

Pg 80 #4

Electrical energy is transported away from the dam through wires. The electrical energy is converted into many different forms of energy and is used in many different ways. For example, at a concert or a play, electrical energy is converted into light and heat by lighting systems and into sound energy by sound systems.

pg 81 #3

Kinetic energy is used to turn turbines. This mechanical energy is converted into electrical energy by generators.

Pg 81 #2

Potential energy is converted to kinetic energy when the water moves through the tunnel.

Pg 80 #2

Some of the water is allowed to flow through a tunnel within the dam. The potential energy in the stored water changes into kinetic energy when the water moves through the tunnel.

Pg 80 #3

The kinetic energy of the moving water turns turbines within the dam. The water's kinetic energy becomes kinetic energy in the turbines. The kinetic energy of the turning turbines is converted into electrical energy by electrical energy.

Pg 80 #1

The water is held behind the dam has the potential energy because of its position.

Pg 81 #1

Water held behind the dam has potential energy.
