Basic Definition: |
The energy of matter that can be released by combining or splitting atoms |
The energy stored in the bonds between the atoms in molecules |
The energy of motion |
The energy stored when magnets are pulled apart and attract or repel |
The energy that can be stored when materials are stretched or pressed into new shapes |
The energy stored when something is lifted against the force of gravity and can then fall |
The energy in electromagnetic waves like light or x-rays |
The energy in moving electrons |
The energy of vibrating materials. |
Heat in the wiggling of atoms (a kind of kinetic energy) |
Example: |
This is how energy is produced in the sun or in a nuclear power plant. |
The gummy bear has energy in the bonds between the atoms in the molecules of sugar that makes it up and this can be released as heat, light and sound when we burn it. |
A running elephant has the energy of movement. |
A magnet held near a piece of steel will pull the steel and make it move. |
A stretched rubber band, balloon, spring, or compressed air can be let go and release its stored energy in a whoosh or whap of sound or as motion energy. |
A car at the top of the hill (with an elephant inside it) has energy that can be released when it rolls down due to its gravity. |
Sunlight can fall on an object and heat it up or can fall on a solar electric panel and make electricity. |
The electrons flowing through your computer can make it hard drive whir. |
Your vocal cords vibrate might make someone's eardrums vibrate and warm up with the sound of "I love you. |
temperature is the measure of the average wiggling, and heat is the sum of all wiggling energy. All energy transfer chains end as heat. |
