Classifying Energy Directions: Have students classify energy as either potential or kinetic, explain and give examples. Example: Energy Potential or Explanation Sources Form Kinetic? Sound kinetic Sound is a type of kinetic energy because it is a vibrating guitar caused by the vibration – or movement - of an string, vocal object. cords Nuclear Energy Sound Energy Nuclear energy is stored energy that Sound occurs when energy travels through holds the nucleus of an atom together. If substances like air or water and causes them to the nucleus of an atom is split or fused vibrate in waves. For example, with another atom, this sound occurs when air moving releases huge amounts past your vocal cords causes of energy. The sun vibrations or the string of a guitar and uranium both is plucked and starts to vibrate. possess nuclear energy. Chemical Energy Gravitational Energy Chemical energy is energy that is Gravitational energy is stored energy that an stored in the bonds between atoms object has because of its height or molecules. Food is made of above the earth. More height chemicals that store and more mass increase the energy. So are gasoline, gravitational energy of an coal, and plants. object. A ball thrown into the air or water at the top of a mountain both have this type of energy. Electrical Energy Heat Energy Electrical energy is the energy of Heat (thermal) energy is the movement of the charged particles called electrons. This atoms and molecules in a substance. As energy can move through wires and something heats up, other materials that this movement increases. conduct electricity, or it Heat energy can be can move on its own emitted by the sun, fire, (for example, the earth’s core, and friction as lightning). caused by movement. Light Energy Motion Energy Light energy is a type of energy that Motion energy is the energy that a moving travels in waves. Sunshine, object has. Wind, running fire, and lightbulbs water and a rubber band all emit light. Radiant shooting through the air all energy is another possess the energy of name for light energy. movement. The faster they go, the more energy they have!

Sound is a type of kinetic energy because it is a vibrating guitar caused by the vibration – or movement - of an sound kinetic string, vocal object. cords Chemical energy describes energy that is Gasoline, chemical potential stored in the bonds between atoms. Coal, Plants The movement of electrons produces electrical kinetic electricity. Lightning Heat describes the movement of the atoms Sun, heat kinetic and molecules of a substance. Fire, the earth’s core Sun, fire, light kinetic Light is a type of energy that travels in lightbulbs waves. Wind, running Since kinetic energy is described as the water, motion kinetic energy of motion, then objects or systems shooting in motion are definitely a form of kinetic rubber band energy! Nuclear energy is energy that is stored Uranium, the nuclear potential within an atom’s nucleus. sun Water at the Gravitational energy is energy that an top of a object or system has, or is stored, because gravitational potential mountain, ball of its position. thrown in the air .
