|
** biomass energy |
any organic material that can be burned as a source of fuel -wood -corn -animal manure -animal/plant oil |
|
|
** chemical energy |
energy stored in a substance (in the bonds of atoms and molecules). may be converted to or from electrical energy, heat energy, or light energy |
|
|
** electrical energy |
results from charged particles. When moving through a wire - kinetic energy When stored in a battery - potential energy |
|
|
** energy |
the ability to perform work, cause motion, or create change |
|
|
** heat energy |
the internal energy of a system or object. means the same as thermal energy. |
|
|
** kinetic energy |
energy of motion. -moving objects -wind -flowing water |
|
|
** mechanical energy |
the sum of kinetic energy and potential energy in a system |
|
|
** potential energy |
stored energy due to the position or condition of the object. has the ability to change into other forms of energy. - example - water stored behind a dam has gravitational potential energy. When the water is released, the potential energy is converted to kinetic (moving) energy |
|
|
** sound energy |
energy traveling through a substance in regular vibrations (waves) |
|
|
** water energy |
kinetic energy of moving water that is harnessed by the use of devices to turn generators that convert energy of motion into electrical energy -running water -falling water -waves -tides |
|
|
** wind energy |
kinetic energy of moving air that is harnessed by the use of wind turbines to turn generators that convert energy of motion into electrical energy |
|
|
** light energy |
energy that can travel through space and time |
|
|
** Decibels (dB) |
units used to measure sound |
|
|
** Conduction |
The movement of heat between two solid objects that are in contact with each other (Like a chocolate bar in your hand) |
|
|
** Convection |
When heat moves between gases or liquids (Like lemonade with ice) |
|
|
** Radiation |
Heat moving directly from one object to another without being carried by matter. Can go long distances. (Like the heat you feel from the sun) |
|
|
** temperature |
Used to measure how hot or cold something is |
|
|
** Shadow |
The dark area behind an object that has blocked light |
|
|
** Reflection |
When light bounces back off an object. Smooth and shiny objects reflect light well (like a mirror or some metals) |
|
|
** Refraction |
When light bends as it goes through something (Like when your body looks strange in the pool because light bends in the water) |
|
|
** Renewable energy |
Energy that will most likely never run out (wind, water) |
|
|
** Non-renewable energy |
Energy that we are not guaranteed to always have available to use (Fossil fuels like gas and coal) |
|
|
** Isaac Newton - The Law of Conservation of Energy |
Energy can neither be created nor destroyed; it transforms from one form to another |
|
|
** Translucent |
allowing light, but not detailed images, to pass through |
|
|
** Transparent |
Clear |
|
|
** Opaque |
Not able to be seen through, no light goes through |
