In a Newtons cradle the ball at one end of the ball train moves with similar velocity to the other minus the gradual slowing due to loss of energy in both.
What would be the result if I made a Newtons cradle in which the size/mass of the balls gradually decrease?
My instinct tells me that the small ball will move with several times grater velocity then the large ball but not sure why. Also assuming that assertion in correct is it necessary to have a great number of balls of different sizes, what is the minimum number that would result in the same velocity difference?
