This predictable transfer illustrates how quantity of motion and kinetic energy persist through the system, even as they shift between the moving spheres. In an ideal elastic collision, the total kinetic energy before impact equals the total kinetic energy after impact.

This symmetry reinforces the concept that the system cannot generate or destroy motion; it can only redistribute it according to physical laws. Elastic Collisions and Energy Transfer Newton's cradle also vividly demonstrates elastic collisions, where kinetic energy is preserved rather than converted into heat or deformation.
Applications and Educational Significance Beyond the classroom demonstration, the principles illustrated by Newton's cradle appear in engineering fields such as vehicle crash testing and sports equipment design. Real-world deviations arise from air resistance, friction, and material imperfections.

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