Desk swinging balls

Then, instead of all four remaining balls swinging out, only the ball on the opposite end jumps forward, leaving its comrades behind, hanging still. For identical elastic balls of any type with initially touching balls the action is the same for the first strike, except the time to complete a collision increases in softer materials. The size of the steel balls is limited because the collisions may exceed the elastic limit of the steel, deforming it and causing heat losses. It was featured more prominently as a series of clay pots in Rosencrantz and Guildenstern Are Dead , and as a row of Eero Aarnio bubble chairs with scantily-clad women in them in Gamer. If you insist on kicking it old school, there's an Earth spinning globe, too. In , an episode of the Omnibus podcast , featuring Jeopardy!

The ball on the opposite side acquires most of the velocity of the first ball and swings in an arc almost as high as the release height of the first ball. You witness this conservation of momentum as the last ball swings into the air with nearly the same momentum as the first ball. It was used to represent the unyielding position of the NFL towards head injuries in Concussion. Archived from the original on 28 September Applying the two conservation equations to solve the final velocities of three or more balls in a single collision results in many possible solutions, so these two principles are not enough to determine resulting action. When this occurs, the complete solution method described below must be used. Morin has been credited as being the first to name and make this popular executive toy.
