The ratio of magnitude of velocity and speed is always:
Asked by Nava Shreya | 11 May, 2013, 12:35: PM
answered-by-expert Expert Answer
Since magnitude of velocity is called speed. But this depends on whether you are talking about instantaneous speed and instantaneous velocity or you are referring to the average velocity and average speed.
 
If you are talking about instantaneous velocity, then instantaneous speed will be equal to the magnitude of instantaneous velocity and in this case the ratio will be 1.
 
If you talk about average velocity and average speed, average velocity is always less than or equal to average speed. So in this case the ratio will always be less than equal to 1.
