Swinging balls action and reaction

Action. The students swing one of the balls out and observe what happens when it is released and The action-reaction force pair is the force due to ball.

Newton's cradle is a device that demonstrates conservation of momentum and energy using a . For the simple solution to precisely predict the action, no pair in the midst of colliding may touch a third ball, because the presence of the third ball .

But in a real Newton's cradle the fourth ball swings out as far as the fifth ball.
