The rigidity of the steel balls and the brief contact time ensure that energy loss is minimal, enabling the outgoing ball to reach almost the same height as the original swinging ball. Understanding how momentum and energy transfer between objects helps designers create safer structures and more efficient mechanisms.

Role of the Intermediate Balls The balls positioned in the center of the line act primarily as force transmitters rather than energy absorbers. The device remains a staple in physics education because it converts abstract equations into tangible, observable motion.
If two balls are lifted and released, two balls on the other side will arc upward, maintaining the balance of momentum and energy. The swinging ball possesses momentum equal to its mass multiplied by its velocity, and this momentum must be transferred through the collision sequence.

They collide momentarily with their neighbors and then return to rest, channeling the impact from one end to the other. The intermediate balls primarily serve to transmit force without storing energy.
