Потужність (N, P, W) — робота, що виконана за одиницю часу, або енергія, передана за одиницю часу:
{\displaystyle N={\frac {A}{t}}}{\displaystyle N={\frac {A}{t}}},
де N — потужність, А — виконана робота, t — проміжок часу, за який ця робота виконана.
У системі SI потужність вимірюється у Ватах. Іншою одиницею вимірювання, яка ще й досі широко використовується, є кінська сила (1 к.с. = 735,5 Вт).
