Circular motion
... Recall that a moving object’s average velocity is ∆d / ∆t, so for an object in circular motion, v = ∆r / ∆t. The velocity vector has the same direction as the displacement for circular motion. At any point in the motion of the object as it travels in the circle, the instantaneous velocity vector is ...

... Speed is a measure of the distance travelled over the time taken. The more distance covered by an object during a given time, the faster the speed it is moving. Constant speed occurs when the object travels the same amount of distance at each even time period. When we travel on an object moving at a ...

While agreeing that such a system might be possible, you might feel that it would be totally absurd and ...
