What is Average Velocity?
It is the total distance travelled in a particular diection divided by total time taken
We can say that
Average Velocity = Total Displacement/Total Time Taken
AVERAGE SPEED FORMULA
Average Speed = Total Distance/Total Time Taken
AVERAGE VELOCITY FORMULA
Average Velocity =Total Displacement/Total Time Taken
Summary
Average Velocity may or may not be equal to Average Speed
