Question

An example in which average velocity of a particle is zero but average speed is not zero

Answer 1

Answer:

If it travels any route, at any speed greater than zero, that returns to its starting point, then it's average velocity is zero, but its average speed is non-zero (if it moved at all). This is just due to velocity being a vector, and speed being a (non-negative) scalar)

Answer 2

Answer:

Ex-

Let a boy, Ram went to his school with a constant speed and then come back again with a constant speed.

His school is' x ' in away from his house..

In this case,

Avarage speed= total distance covered / total time taken.

=x+x/total time taken

And,

Avarage velocity =total displacement covered /total time taken

= x-x/ total time taken

=0
