Distinguish between average velocity and average speed . |
|
Answer» Solution :Average VELOCITY: The average velocity is defined as ratio of the displacement VECTOR to the corresponding timeinterval. `vec(V) _("avg")= (Delta vec(r))/(Delta t)` It is a vector quantity . The direction of average velocity is in the direction of the displacement vector `(Delta vec(r))` . Average speed :THEAVERAGE speed is defined as the ratio of total path length travelled by the particle in a time interval. `{:("Average"),("Speed"):}}= {{:("Total path"),("length"),(/"total time"):}` It is a scalar quantity . doesn't possess direction. |
