| Term | Definition |
|---|---|
| work | the transfer of energy by a force acting on an object as it is displaced |
| power | rate at which work is done or the rate at which energy is transferred from one place to another or transformed from one type to another |
| conservation of energy | energy cannot be created or destroyed, but can be altered from one form to another |
| kinetic energy | energy of motion |
| potential energy | energy that is stored in an object due to its position relative to some zero position |
| mechanical energy | the sum of potential energy and kinetic energy |
| system | a specific, defined part of the universe that is being studied; a collection of objects or components that are considered together to analyze their interactions and behavior under specific conditions |
| work-energy theorem | the net work done on an object is equal to the change in its kinetic energy |
| thermal energy | energy in an object or system due to the movement of its molecules and atoms |
