Sym. $P$

$$\begin{array}{rlrl}P(t)& =\frac{\mathrm{d}W}{\mathrm{d}t}& =\frac{\mathrm{d}}{\mathrm{d}t}(\overrightarrow{F}\cdot \mathrm{d}\overrightarrow{r})& =\overrightarrow{F}\cdot \overrightarrow{v}\\ P_m& =\frac{W}{\mathrm{\Delta }t}& =\frac{\overrightarrow{F_m}\cdot \mathrm{\Delta }\overrightarrow{r_m}}{\mathrm{\Delta }t}& =\overrightarrow{F_m}\cdot \overrightarrow{v_m}\\ [P]& =\mathrm{V}\end{array}$$
