|
energy |
ability to do work |
|
|
potential energy |
stored energy |
|
|
kinetic energy |
energy in moving objects |
|
|
gravitational potential energy |
potential energy due to the height of an object |
|
|
elastic potential energy |
energy stored in something that can be stretched or compressed |
|
|
radiant energy |
energy that travels by waves or particles
|
|
|
thermal energy |
total energy of all the particles in an object***everything has thermal energy, because ALL atoms are ALWAYS moving
|
|
|
chemical energy |
energy stored in the chemical bonds of molecules
|
|
|
electrical energy |
energy that is caused by moving electric charges (electrons)
|
|
|
mechanical energy |
energy of movement |
|
|
nuclear energy |
energy from fission or fusion of an atom’s nucleus.
transformation= ___ to heat to mechanical to electrical. a benefit is it releases a lot of energy. a problem is it is radioactive if there is a leak,spent fuel rods are radioactive for 1000 years. |
|
|
energy transformations/conversions
|
the change from one form of energy to another
|
|
|
law of conservation of energy |
energy is transformed from one form to another. No energy can be created or destroyed. Energy is usually lost as thermal energy
|
|
|
What is the formula of potential energy? |
mgh |
|
|
kinetic energy |
½ mv2 |
|
|
joule |
metric unit for energy |
|
|
What is the difference between heat, temperature, and thermal energy? |
heat- how we move energy thermal energy-total kinetic energy temperature- average kinetic energy |
