When is the average speed of a particle moving along one straight line less than the magnitude of its average velocity over the same time interval?

To determine

For a particle in a straight line motion, when is average speed smaller than average velocity.

Explanation of Solution

Write the expression for magnitude average velocity

  |v→av|≡|Δx→|Δt (I)

Here, Δx→ is the displacement, Δt is the time interval, and v→av is the average velocity
