transformation energ
transformation of energy
| Question | Answer |
|---|---|
| Transfer or use of energy | work |
| energy in motion | kinetic |
| ability to do work | energy |
| stored energy an object has because of it's postion | potential energy |
| Energy produced by moving electrons | electrical energy |
| energy that occurs when bonds are broken between atoms. energy of a compound that changes as atoms are rearranged. | chemical energy |
| energy resulting from the random motion of molecules | thermal energy |
| energy that occurse when atoms are joined by fusion or split by fission. Changes in the nucleus of an atom. | nuclear energy |
| energy that is a result of light and other forms of radiation which travels in waves | electromagnetic energy |
| energy that involves movement. Involves motion and position of an object | mechanical energy |
| energy that occurs due to a vibrating object transmitting energy through air | sound energy |
| energy is changed from one form to another | energy conversion |
| states that energy can neither by created nor destroyed but changed into different forms energy | law of conservation of energy |
| in electromagnetic energy and sound energy, the energy travels in what? | waves |
| In nuclear energy, when the nucleus of atoms are split, this is called | fission |
| In nuclear energy, when the nucleus of atoms are joined, this is called | fusion |
| kicking a soccer ball is an example of potential or kinetic energy? | kinetic |
| gasin a fuel tank is an example of potential or kinetic energy? | potential |
| a bird flying is an example of potential or kinetic energy? | kinetic |
| a streched rubber band is an example of potential or kinetic energy? | potential |
| Identify the form of energy found in a telephone | sound or electrical |
| Identify the form of energy found in a microwave | nuclear |
| Define energy | Stored work (the capactity to do work) |
| the transfer of energy to an object by using a force that causes the object to move in the direction of the force. | WORK |
| What are the 2 requirements for work to be done | Force must be exerted on an object and object must move in the same direction as force |
| Total kinetic energy of a substance | thermal energy |
| a beaker of water will continue to lose heat until it reaches room temperature | thermal equilibrium |
| when two object touching each other reach the same temperature they have reached | thermal equilibrium |
| Heat transfer only occurs from: | warmer objects to colder objects |
| transfer of heat energy by electromagnetic waves through empty space is called | radiation |
| When heat is being transferred between two objects the objects have --------- temperature | different |
| temperature at which matter no longer moves | absolute zero |
| transfer of thermal energy through a substance by direct contact | conduction |
| transfer of heat by the movement of particles in a liquid or gas | convection |
| Weather in the US uses what scale | fahrenheit |
| measure of the average kinetic energy of all the particles in an object | tempertature |
| Scientist use what scale to measure absolute zero | kelvin |
| movement of thermal energy from warmer to cooler object is called | heat |
