Explain that a can have zero average velcoity but not zero average speed.

A body have zero average velocity but not zero average speed. Justify.

Explain average velocity and average speed.

When does the average velocity become zero ?

When does the average velocity become zero?

When does the average velocity become zero?

Distinguish between average velocity and average speed. Is it possible that the average velocity of a body is zero, but its average speed is non-zero?

Can a body have a. Zero instantaneous velocity and yet be accelerating? b. Zero average speed but non-zero average velocity? c. Negative acceleration and yet be speeding up? d. Magnitude of average velocity be equal to average speed ?

A : If speed of a particle is never zero than it may have zero averag speed. R : The average speed of a moving object in a closed path is zero.
