# Power

on . Posted in Classical Mechanics

Power, abbreviated as P or PWR, is the rate of doing work or the rate of using energy per unit time.

## Power with displacement formula

$$\large{ P = \frac{F \; d}{t} }$$
Symbol English Metric
$$\large{ P }$$ = power $$\large{W}$$ $$\large{\frac{kg-m^2}{s^3}}$$
$$\large{ d }$$ = displacement $$\large{ft}$$ $$\large{m}$$
$$\large{ F }$$ = force $$\large{lbf}$$ $$\large{N}$$
$$\large{ t }$$ = time $$\large{sec}$$ $$\large{s}$$

## Power with Velocity formula

$$\large{ P = F \; v }$$
Symbol English Metric
$$\large{ P }$$ = power $$\large{W}$$ $$\large{\frac{kg-m^2}{s^3}}$$
$$\large{ F }$$ = force $$\large{lbf}$$ $$\large{N}$$
$$\large{ v }$$ = velocity $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$

## Power with Work formula

$$\large{ P = \frac{W}{t} }$$
Symbol English Metric
$$\large{ P }$$ = power $$\large{W}$$ $$\large{\frac{kg-m^2}{s^3}}$$
$$\large{ t }$$ = time $$\large{sec}$$ $$\large{s}$$
$$\large{ W }$$ = work $$\large{lbf-ft}$$ $$\large{J}$$
