GCSEPod® Physics - Work and Power

**This is a short sample from GCSEPod® Physics - Work and Power. The full title is over 20 minutes long and includes 6 Chapters. **

In this title, you will learn about some of the different types of energy: gravitational potential, elastic potential and kinetic energy. Gravitational potential energy is the energy that an object has because of its position in a gravitational field. Elastic potential energy is the energy stored in a stretched elastic object, such as a rubber band or a spring, and kinetic energy is the energy of an object that is moving. You will also learn about how forces transfer energy to heat, and the role this plays in creating waste energy. This prevents processes from being 100% efficient. The title will explore work done', how it relates to energy transfers, and how it is calculated from the exertion of a force over a distance. Finally, you will learn about the rate of doing work, and how power is calculated.
