Balls HD

In practice the central collisions of identical balls can be observed with the aid of set-up shown in animation. All the balls are suspended on long strings and the task is reduced to consideration of their paired collisions. Thus, all the system will behave as shown in animation, i.e. outermost balls will be pushed consequently with identical velocity and deviated by identical angles, while all the balls between them will be in rest. It is necessary to note, that above mentioned consideration is true only for the case of absolutely elastic central collision of the balls when there is no loss of energy. Actually, the total energy of the system will decrease due to air dumping, heating of the balls, excitation of acoustic waves, etc. Therefore, the amplitude of extreme balls deviation decreases with time and the central balls are set into the oscillatory motion.

In our consideration we suggested a series of two ball collisions, so that the last ball in the line leaves the group with approximately the same velocity as the ball which struck the group originally. If the contact between the balls is rigid, the incoming ball would see a single massive object comprised of several balls. It would then rebound from the collision in accordance with the rules developed above for collision between different masses. Our reasoning leads us to conclude that even though the balls in the line appear to be in contact, there must be initially a very soft reaction between adjacent balls.
