Speed, abbreviated as s, is the rate of change or distance with time.  Speed is a scalar quantity that measures how fast an object is moving, regardless of its direction.  It is the magnitude of velocity and does not take into account the object's motion in a specific direction.

Unlike velocity, speed does not consider the object's displacement or change in position.  It only reflects the rate at which an object covers a certain distance.  Speed is a fundamental concept in physics and is used to describe the rate of motion of various objects.  It is particularly useful in scenarios where direction is not a significant factor or when considering the overall magnitude of motion.


speed formula

\( s \;=\; d \;/\; t \) 
Symbol English Metric
\( s \) = speed \(ft\;/\;sec\)  \(m\;/\;s\) 
\( d \) = distance \( ft \) \(m\)
\( t \) = time \( sec \) \( s \)
