Aim: To distinguish between forms of energy and source of energy; to classify the different forms of energy. Kinetic or potentital. Key words: Kinetic, Potential Focus Question: What is energy? Energy is the ability to do work. (To make a change happen). Definitions: Sources: Where we get the energy from. Such as sun, coal, wind and oil. Forms: The kind of energy that we can observe such as light, heat and movement. Gravitational - the potential energy held by an object because of its high position compared to a low position. Chemical - energy stored in the bonds between atoms that is released by a chemical reaction. Nuclear - the splitting of uranium atoms to create energy by fission. Elastic - the energy stored by stretching an object. Motion - the kinetic energy an object has due to its motion. Heat/thermal - the kinetic force of the hot, fast moving atoms. Electrical - the kinetic energy that comes from charged particles which forms electrical current. Sound - the energy coming from the vibration of matter. Light - is energy that travels by waves or particles. Below are some images from the lesson. First was Izaak's sheet Then my sheet from today's lesson. Lesson Summary:
