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! An Introduction to Biomass

Answer Key: Heat describes the movement Chemical energy describes energy that is caused by the vibration – Sound is a type of kinetic energy because it is Light is a type of energy that travels in The movement stored in the bonds between atoms. and molecules of a substance. Classifying Energy
