Potential energy is stored energy. Energy Test Study Guide Test Nov. 3 Energy is the ability to do work or cause change. The Law of Conservation of Energy states that energy cannot be created or destroyed. It may be transformed from one form into another, but the total amount of energy never changes. A stretched rubber band A ball at the top of a hill Kinetic energy is the energy an object has due to its motion. Heat energy is the transfer of thermal energy. Chemical energy is energy stored in particles of matter. . Kinetic energy increases as an object moves faster The bike rider going up or down the hill The ball falling to the ground Friction Sun (as thermal energy ) Radiation Fire When we eat our body uses chemical energy as fuel to help up grow Chemical energy can also be stored in batteries ,matches fuel Electrical energy is the energy flowing in an electric circuit. Electrical energy can be transformed into light or motion, and can Mechanical energy is the energy due to the motion and position of an object. Every object in motion contains mechanical energy. produce thermal energy/ Heat. Machines such as steam engines can convert mechanical energy into other forms of energy. The electric motor makes mechanical energy from electrical energy while a generator performs the opposite. EXAMPLES OF ENERGY TRANSFER
