Question
You run one lap around a 400 m circular track in a time of 10 s. What’s your average velocity?
Solution
The average velocity is calculated by dividing the total displacement by the total time. In this case, since you're running in a circular track and ending up at the same point you started, your displacement is 0 (displacement is a vector quantity that takes into account the starting and ending point, not the path taken). Therefore, your average velocity is 0 m/s.
