Stored Energy

The video tutorial explains potential energy as stored energy that can transform into other energy forms. It covers how the body stores energy in sugar, which is used during movement, and compares it to gasoline in cars. Chemical energy is discussed in the context of metabolism and battery function. Elastic potential energy is illustrated with rubber bands, while fuel's conversion to kinetic energy is shown with engines. Human energy types are linked to exercise, and potential energy in water and bicycles is explored. The video concludes by encouraging viewers to identify potential energy in everyday objects and community resources.

What happens to your body when it runs low on sugar?

• It becomes more energetic.

• It becomes too tired to move.

• It starts storing more energy.

• It starts burning fat instead.

How do batteries store energy?

• By storing sound waves.

• By storing light energy.

• By storing electrons.

• By storing chemicals.

What type of energy does a stretched rubber band have?

• Potential energy

• Thermal energy

• Kinetic energy

• Electrical energy

What happens when the engine of a lawn mower starts?

• The engine parts gain kinetic energy.

• The gasoline turns into potential energy.

• The lawn mower stores more energy.

• The spark creates electrical energy.

What is an example of potential energy in a community?

• A working light bulb

• A moving bicycle

• Coal stored for power generation
