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

\(\large{ s = \frac{ d }{ t }   }\) 

Where:

 Units English Metric
\(\large{ s }\) = speed \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
\(\large{ d }\) = distance \(\large{ ft }\) \(\large{ m}\)
\(\large{ t }\) = time \(\large{ sec }\) \(\large{ s }\)

 

Related Speed formula

\(\large{ s = \frac{ 5252\; HP }{ \tau } }\) (engine horsepower)

Where:

\(\large{ s }\) = speed

\(\large{ HP }\) = horsepower

\(\large{ \tau }\)  (Greek symbol tau) = torque
