How is solar energy used to create electricity?

Back

Solar energy is harnessed from sunlight using solar panels, which convert sunlight into electricity through photovoltaic cells.

Front

What type of energy is produced by vibrating objects, such as guitar strings?

Back

Sound energy is produced when objects vibrate, creating sound waves that travel through the air.

Front

What is heat energy and how is it used in cooking?

Back

Heat energy is the energy that comes from the temperature of matter. It is used in cooking to transfer heat to food, making it hot and ready to eat.
