We have a Newtons cradle , when you let go of one ball at one end you know what happens. Rlease one ball and the other side has a ball osciallte.
But if you release two balls (with a 5 ball cradle) , why is that two balls on the other side of the middle ball also rise in response. How does the system "Know" we have released two balls? Why doesn the other side just have one ball oscillating higher?
