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.

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