Question

26. Give an example of situation in which speed of a body is not equal to its velocity. When is the velocity of a body is uniform?Can a moving body have zero average velocity? Illustrate with example​

Answer 1

In circular motion speed will be constant but velocity changes.

Velocity is uniform if there is equal displacement in equal intervals of time.

Av. valocity can be zero if the initial and final vel equals to zero.

Ex: av velocity=v1 + v2/ time

If v1 +v2= 0

av vel = 0

Hope this answer helps U
