# Speed

on . Posted in Classical Mechanics

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

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