- Energy can also be
stored in many other ways. Batteries, gasoline, natural gas, food, water
towers, a wound up alarm clock, a Thermos flask with hot water and even pooh
are all stores of energy. They can be transferred into other kinds of energy.
- Heat energy from the
sun is transferred to water bodies. This warms the water up. The result is
stored thermal energy. The warm water heats the air over it. Warm air rises, so
the air is now set into motion. The moving air now has kinetic energy.
- If you look
at a battery, it will have two ends: a positive terminal and a negative
terminal. If you connect the two terminals with wire, a circuit is formed.
Electrons will flow through the wire and a current of electricity is produced.
