Give Reasons for the Following:

In a long distance race, the athletes were expected to take four rounds of the track such that the line of finish was same as the line of start. The motion of the athlete is non-uniform. Why?

Answer :

The athlete was expected to take four rounds such that: line of finish = line of start

This means, we are saying that athlete comes back to its initial position. This is only possible if there is change in direction.

Without the change in direction a person can never reach back the initial point.

Now, we know that change in direction means acceleration, hence motion is non uniform.
