How is average velocity different from instantaneous velocity?

Explanation

Average velocity: It is the ratio of total displacement to total time taken. It is independent of path of the body.
`therefore`Average velocity `=(s_2-s_1)/(t_2-t_1)`
Velocity of a particle at a particular instant of time is known as instantneous velocity. Here time interval is very small.
Only is uniform motion, instantneous velocity= average velocity. For all other cases instantneous velocity may differ from average velocity.
