Difference between speed and velocity and average speed and velocity
Asked by Shreeya | 08 May, 2012, 06:57: PM
answered-by-expert Expert Answer
The term speed means only the magnitude of the speed of the particle at any defined point.
When the direction of motion is included in this speed, it becomes a vector quantity called velocity at any given point. Now , when this speed is defined for a interval of time then it becomes average speed. And when direction is included in this average speed , it again refers to the average velocity.
