Describe a situation where an object has a change in velocity but constant speed

- - the little ball going round and round a spinning roulette wheel

- - a car driving around a curve in the road at a constant speed

- - any Earth satellite in a perfectly circular orbit.

The closest thing to it is a geostationary TV satellite ... they try hard

to make those orbits perfectly circular, and keep correcting them to

stay circular.

Speed does not depend on direction, but velocity does.

So, when their is a direction, the velocity would change, but speed would remain constant.
