Do potential energy and kinetic energy have same dimensions?

In fact, whenever you have quantities that are being added in any physics equation, those quantities must have the same dimensions. Let kinetic energy be T, and let potential energy be U. read more

Yes. In fact, whenever you have quantities that are being added in any physics equation, those quantities must have the same dimensions. Let kinetic energy be T, and let potential energy be U. The law of conservation of energy is [math] T_0 + U_0 = T_1 + U_1 [/math] Since we can add the two types of energies, they must have the same dimensions. read more

Potential energy of other types will have the same dimensions. Calories are equivalent to Joules (1 calorie = 4.2 Joules) for example, and we can also write nuclear energy as Joules if we want to, though scientists use electron-volts instead, but they have the same dimensions. read more
