Energy can be converted from one form to another.
Examples:
- Gasoline (chemical) is put into our cars, and with the help of electrical energy from a battery, provides mechanical (kinetic) energy.
- Purchased electricity is fed into our TVs and is converted to light and sound.
- Similarly, purchased electricity goes into an electric bulb and is converted to visible light and heat energy.
- The image below shows examples of more conversions.
