Average Velocity

Average Velocity

Average velocity is defined as the ratio of total displacement of the object to the total time taken. It is expressed as: 

Average Velocity (v_{AB}) = frac{Total: displacement }{Total: time: taken}

The unit of Average velocity is meter per second(m/s). Displacement differ from distance in the fact that displacement depends on the magnitude as well as the direction.

For example :

Suppose, a car travel from point A to B and back to A . In this case no displacement occur or we can say that velocity is zero but distance travelled by the body is the sum of distance traveled from A to B and B to A, so speed will not be zero.
