Average Speed and Average Velocity

The average velocity of a particle is zero but not its average speed. is it possible?

Asked Prashant

Answer:

Yes, it is possible. As you may probably know, Average speed is the ratio of distance traveled by a body to the time taken whereas average speed is the ratio of displacement to the time taken. The displacement made by a body can be zero when the body returns to its original path. abut, the distance which the total length of the path followed by the body cannot be zero.

Therefore the average velocity of a particle is zero but not its average speed. is it possible?
