Energy and Energy Transformations
| Question | Answer |
|---|---|
| energy | the ability to cause change |
| kinetic energy | energy due to motion |
| potential energy | stored energy due to the interactions between objects or particles |
| work | the transfer of energy that occurs when a force makes an object move in the direction of the force while the force is acting on the object |
| mechanical energy | the sum of potential energy and kinetic energy in a system of objects |
| sound energy | the energy that sound carries |
| thermal energy | the sum of kinetic energy and potential energy of the particles that make up an object |
| electric energy | the energy an electric current carries |
| radiant energy | the energy that electromagnetic waves carry |
| nuclear energy | energy that is stored and released in the nucleus of an atom |
| law of conservation of energy | energy can be transformed from one form into another or transferred from one region to another, but energy cannot be created or destroyed |
| friction | a force that resists the sliding of two surfaces that are touching |
