Average speed is always equal to magnitude of average velocity. Is this statement true or false?
it is true the velocity is a vector but it's magnitude is scalar i.e speed
In Exercises 3.13 and 3.14, we have carefully distinguished between average speed and magnitude of average velocity. No such distinction is necessary when we consider instantaneous speed and magnitude of velocity. The instantaneous speed is always equal to the magnitude of instantaneous velocity. Why?
The ratio of average velocity to average speed is 1 always equal to Unity 2 always greater than Unity 3 always less than Unity or 4 may be less than or equal to Unity
