Answer:
Key Difference: Velocity refers to the rate of change of distance with respect to time. It is a vector quantity, which means that it has both - a direction and a magnitude. Average velocity refers to the average total displacement over the time of travel. ... It can also be referred to as a speed with a direction.

Velocity: The rate at which a distance changes over time.
Average velocity: Average total displacement over the time of travel.
Formula:
- Velocity=
- Average velocity=
Purpose:
- The velocity of a moving item is used to determine its speed and direction.
- Average velocity is used when displacements are corresponding to the various time taken.
Example:
- If the vehicle comes back to its starting position, then there will be no displacement. Therefore, the velocity will be zero.
- If a substance moves along the x-axis, it is at 5 meters in 3 seconds and 7 meters at 5 seconds. Then the average velocity will be = 1m/s.
