Question

Distinguish between average speed and average velocity

Answer 1

Difference between Average Speed and Average Velocity:
Definition:
Average speed is the total distance traveled divided by the time. Speed takes into account the total path length traveled.

Average velocity is the displacement divided by the time. Velocity only takes into account the starting and ending points of an object’s path.

Direction:
Average speed has no specific direction. It is a scalar quantity.

Average velocity has a specified direction. It is a vector quantity.

Answer 2

The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero.


Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time.
