|
Torque |
A quantity that measures the ability of a force to rotate an object around some axis. |
|
|
Ultraviolet catastrophe |
Failed prediction of classical physics that the energy radiated by a blackbody at extremely short wavelengths is extremely large and that the total energy radiated is infinite. |
|
|
Work |
The product of the component of a force along the direction of displacement and the magnitude of the displacement. |
