Distinguish between average speed and average velocity.

answered-by-expert Expert Answer

Average speed is the ratio of the total distance travelled by the body to the total time of journey, it is never zero.

If the velocity of a body moving in a particular direction changes with time, then the ratio of displacement to the time taken in entire journey is called its average velocity.

Average velocity of a body can be zero even if its average speed is not zero.
