Energy Unit Test
 What are the two types of energy?
 What is Work?
 Define kinetic energy.
 What two variables affect the amount of kinetic energy that an object has?
 What happens to kinetic energy as mass and speed increase?
 Define potential energy.
 What is meant by energy of position?
 What force affects potential energy due to position?
 What is meant by stored chemical energy?
 Give an example of potential energy due to position and potential energy due
to chemical composition.
 How is the compression of an object considered potential energy?
 Students should be able to identify examples of kinetic and potential energy.
 According to the Law of Conservation of Energy, energy is never lost.
 In every transformation, some energy is always transferred into thermal
energy (heat). This is called a byproduct. Sound can also be a
byproduct. For example, a blender creates noise and heat when the
blade is spinning, but that is not the purpose of a blender. Therefore,
heat and sound are byproducts.
 Burning a candle is Chemical to Electromagnetic
 Walking across a floor is Chemical to Mechanical
 Photosynthesis is Electromagnetic to Chemical
 Battery making clock hands move is Chemical to Electrical to Mechanical
 Burning firewood is Chemical to Thermal and Electromagnetic and Sound
 A swing will eventually stop because of friction
 A blender blending food is Electrical to Mechanical
 A hydroelectric power plant turns Mechanical to electrical energy
 Shouting into a cave is you turning mechanical energy into sound
 Turning on a radio is turning electrical energy into sound
 A lamp turns electricity into Electromagnetic
 Eating provides you with chemical energy to move.
 All animals turn chemical energy into mechanical energy when they move.
 Burning fossil fuels releases energy that originally comes from the sun
because fossil fuels come from plant and animal remains.
 You will need to know the definitions of the forms of energy found in your
notes
