- Electrically – By an electrical current.
- By radiation – By Light waves or Sound waves.
- By heating – By conduction, convection or radiation.
Is a TV kinetic or potential energy?
Potential energy is all around us as we go about our day-to-day tasks. In the home, a light bulb that isn’t on has potential energy, while a television that is off does as well. Ovens that are not turned on are displaying thermal potential energy.
