Q: A cyclist rides round a circular track at a steady 20m/s. Is this a case of uniform velocity? Explain your answer...

I think the answer is no becuase a circular track means that the cyclist will return to their point of origin with each lap and therefore there is no real displacement.

Am I right or is there more to add to my answer?

Any guideance or help would be appreciated.

Speed is constant (20m/s), but velocity is NOT constant, because of the change of direction. Going around a circular track means that direction is constantly changing, which means acceleration (ie not uniform velocity).
