# Speed

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Speed, abbreviated as s, is the rate of change or distance with time.  Speed is a scalar quantity having no direction.  Speed is not velocity, they do not mean the same thing.

## speed formula

$$\large{ s = \frac{ d }{ t } }$$
Symbol English Metric
$$\large{ s }$$ = speed $$\large{\frac{ft}{sec}}$$  $$\large{\frac{m}{s}}$$
$$\large{ d }$$ = distance $$\large{ ft }$$ $$\large{ m}$$
$$\large{ t }$$ = time $$\large{ sec }$$ $$\large{ s }$$
