Hey there


Let me tell you first what is the mean of average velocity and average speed is .

•Average velocity :-

Average velocity is the total displacement of any object in particular time t


•Average speed :-

it is the total distance covered by the body in period of time

→ Note :- the main difference is that velocity is expressed in terms of Displacement and speed in terms of distance

Let me understand you an example

A car is moving along a straight line Say OP it moves from O to P in 18 second and returns from P to Q in 6 second what are the average velocity and average speed of the car in going from 0 to P and back to Q

we know

Vage \:  \:  =  \frac{dispacement}{time \: }  =  \frac{240}{18 + 6}  =  + 10 \:  {ms}^{ - 1}  \\  \\ Sage =  \frac{path \: length}{time}  = (360 + 120 )\div 24 =  \frac{480}{24} = 20 \:  {ms}^{ - 1}
We can easily see

• Average velocity isn't equal to average Speed


•The motion which is involved over here changes in direction

•Therefore the path length magnitude is greater than of the magnitude of Displacement


Hope this helps you ☺

Answer:

Yes, this is possible.

Explanation:

  • We can consider that a particle starts from point A and moves to point B and returns to A again with an average speed of v.
  • Average speed is the distance covered per unit of time.
  • Average velocity is the displacement per unit time.
  • Displacement is the shortest distance between an object's initial and final points.
  • In the case we have considered, the particle has returned to its original position, so the displacement is 0.
  • Since the displacement is 0, the average velocity is also 0.
  • Considering this example, the average speed is not 0, it has some value but the average velocity is 0.

It is possible for the average velocity to be zero when its average speed is not zero.
