Potential and kinetic energy
Key Info
- Title: Potential and kinetic energy
- Duration: 01:01
- Description: Stella explains how the potential energy in a bucket of water is transferred into kinetic energy as it drops and turns a wheel. As the wheel turns it powers a dynamo and the kinetic energy is converted to electricity, sound and heat. Finally the electrical energy is transferred to a radio and is converted to sound and some heat. About 6% of the potential energy in the bucket of water is eventually converted into sound energy in the radio.
- Subject: Physics Topic: Energy and Radioactivity
