Potential energy Stretched string The energy possessed by a body due to its position is known as potential energy. Example for potential energy is a stretched string. Potential energy is a form of mechanical energy. Wind energy Windmills The energy produced by wind is called wind energy. It can be used to produce electricity. Wind energy is available in abundance in nature and does not cause pollution. Windmills are used to generate electricity from the wind. Electrical energy Washing machine Electrical energy is generated in power plants and is a form of energy used to run appliances that are electrical. Electrical appliances such as television, computer, fans and music systems run on electrical energy. Sound energy Guitar When force is applied on an object, it produces vibrations. These vibrations reach our ears as sound. This is how musical instruments such as guitar strings and drum skins produce sound. Light energy Torch Light is a form of energy. It enables us to see things around us. The sun, burning candle, electric bulb and fire, all give out light energy. Column A Column B 1. Potential energy c. Stretched string 2. Wind energy e.
