### Potential and Kinetic Energy Power Point and audio

1. 1. Potential & Kinetic Energy
2. 2. Energy can be divided into two states: • Potential • Kinetic Source: http://need-media.smugmug.com/Graphics/Graphics/17024036_Bdmf8C/1289377214_Wk8nb8N#!i=1289377214&k=Wk8nb8N
3. 3. Potential Energy • Stored energy, energy of position • Energy in a body at rest • Due to an objects height • Energy in objects that can be stretched or compressed • PE = weight x height Source: http://energyforkidseducationalwebsite.weebly.com/types-of-potential-energy.html
4. 4. Potential energy can be increased by: • Increasing height • Increasing mass • Increase distance stretched • Compress more Source: http://physics.tutorvista.com/ Source: http://www.weiku.com/products/8340304/comfort_compressed_spring_mattress.html
5. 5. Kinetic Energy • Energy of motion • Energy an object has because it is moving • KE = ½ (mass x velocity²) Source: http://themeparks.about.com/od/photoandvideogallery/ig/Intimidator-305/THAT-s-Intimidating.htm
6. 6. Kinetic energy can be increased by: • Increasing mass • Increasing speed
7. 7. What is the energy change? •Energy cannot be created or destroyed •Energy can change forms
8. 8. In Summary • Potential energy is stored energy. • Kinetic energy is the energy of motion Source: http://openclipart.org/detail/22040/battery-by-nicubunu
