Term | Definition |
---|---|
energy | the capacity to do work |
work | the transfer of energy to an object by using a force that causes the object to move in the direction of the force |
kinetic energy | |
potential energy | the energy that an object has because of the position, shape, or condition of the object |
mechanica energy | the amount of work an object can do because of the object's kinetic and potential energies |
thermal energy | the kinetic energy of a substance's atoms |
the energy transferred between object's that are at differnet temperatures | |
chemical energy | the energy that is stored in the chemical bonds |
electrical energy | the energy that results from the flow of moving charges |
