| A | B |
|---|
| potential energy | energy stored in an object due to its position |
| kinetic energy | energy an object has due to its mass and motion |
| elastic collision | KE same as before and after collision |
| gravitational potential energy | potential energy an object has due to its elevated position |
| 1st law of thermodynamics states | Energy cannot be created or destroyed (it can change forms) |
| 2nd law of thermodynamics | any time energy changes from one form to another, some of the energy changes into heat |
| the equation for kinetic enery | 1/2 Mass X speed squared |
| acceleration due to gravity | 9.81 m/sec2 |
| perpetual motion | a machine that makes as much energy as it uses |
| heat energy | internal motion of atoms |
| thermal energy | sum of all KE of all particles in an object |
| chemical energy | energy that is required to bond atoms together |
| radiant or electromagnetic energy | self-sutaining interaction of fields |
| nuclear energy | the nucleaus, or center of an atom, is the source for this type of energy |
| electrical energy | the ability to do work through the motions of charges |
| absolute zero | the measure of thermal energy where all transmission stops |
| mass energy | the energy equivalent to matter itself |
| energy | the ability to do work |
| partially elastic collision | conserve momnetum but do not conserve kinetic energy |
| inelastic collision | when colliding objects stick together after the collision |
| radiation | the transfer of energy by electromagnetic waves |
| acoustic energy | energy through particle oscillation |
| joules | kg (m squared) / second squared |
| wh | Gravitational Potential Energy |
| 1/2 m v2 | Kinetic Energyy |
