Its dimensional formula is MLT-1. Galileo defined speed as the distance covered per unit of time. Speed DistanceTimeors dt.
Speed in Physics Formula.
Therefore speed is also a scalar quantitySI unit of speed is meter per second other units like kilometer per hour miles per hour feet per second are also used. This is the way the speed of a car is typically measured. In equation form that is displaystyle v frac d t. Distance is a scalar.
