It can also be defined as the total distance travelled divided by ● SPH4U the total time to travel that distance. Instantaneous speed (Vinst or v) is the speed of an object at a instant. ● When a definition has the word "rate", it means Average velocity (Jav) is the rate at which an object is displaced, or the rate of change of It is a vector quantity. This can also be defined as the Vav total displacement divided by the time interval for that change.
