5. Gravitational Potential Energy ___________ Water that is raised up gains potential energy due to its motion against gravity. Gravity wants to pull it down If the water is allowed to move with gravity, it can be used to do something like spin a turbine to generate electricity in a hydroelectric power plant

6. Kinetic Energy _______________ Anything that is moving has kinetic energy If an object gains potential energy by raising it up, it ……………..

Energy Units No matter which form of energy you are talking about, ____________

Energy Transformation Energy cannot be created or destroyed, it can only be converted from one form to another. Examples: The bonds within a piece of wood have chemical potential energy. It releases this chemical energy when it is burned ___________

Energy Transformation Equation Shows the different forms the energy takes as well as the order. Each form of energy is separated by a  Example: A microwave uses electrical energy to create radiant energy (………….. _______________________
