In fact it's wired to calculate and graphically display the trajectory of a ball after it's dropped from a certain height, and bounces on the ground. In practice, the program had a bug in it or a computing element was not functioning right, because when the program ran it would crash just after the first bounce. Probably had to do with the acceleration or velocity changing to the negative direction. If the function of something can be changed, whether the change is in the sequence of bits recorded on a diskette, or the pivot point in a set of linkages, I would say that you are changing the programming of that machine. But that's just my perspective and opinion.
