Question

Give 3 example in which average speed is not equal to the magnitude of average velocity

Answer 1

Average speed is total distance travelled divided by total time taken by object for cover up to that ditance.

Average velocity is total displacemet of object divided by total time taken by object to cover up that distance.

Main thing is time is always same for same object for which you are calculating average velocity or average speed but distance and displacement can be change according to object’s position.

If object is performing uniform accelarated motion in straight line and in one direction then at any time it’s average velocity and average distance will be same.

Answer 2

Answer:

1. When an object is in uniform circular motion

2.When an object returns back to its initial position after covering a distance

3. Motion of sun,moon, etc.

Hope it helps you
