Energy of Motion KINETIC ENERGY | ||
| Conventional view | Fundamental view | |
| ■ Relative motion between inertial frames | MOTION | ■ Relative motion between particle and aether |
| ■ Equals work applied | DEFINED | ■ Defined only by intrinsic speed |
| ■ Observer dependent | OBSERVER | ■ Observer independent |
| ■ No upper limit (depends on force/energy applied) | LIMIT | ■ Has upper limit (when particle attains lightspeed) |
| ■ Precludes mass-to-energy conversion | CONVERSION | ■ Involves mass-to-energy conversion |
| ■ Basic physics; particle physics | USEFULLNESS | ■ Study of gravitational collapse |
| ■ APPARENT kinetic energy | TERMINOLOGY | ■ INTRINSIC kinetic energy |
