ICSE Class 9 Answered
Can the average velocity of a particle be zero when its average speed is not zero?
Asked by hemanginivyas92.9spicertl | 15 Aug, 2020, 09:20: AM
Expert Answer
Average velocity is defined as the ratio of total displacement to total time taken.
Thus, in case when the final position and initial position is same the total displacement will be zero and thus average velocity will also be zero even if the average speed is not zero.
Note" Average speed is ratio of total distance to total time taken. And the distance travelled can never be zero.
