摘要:

A laboratory experiment that demonstrates the simultaneous conservation of angular and linear momentum is described. A disk is positioned on an air table, and pellets from an air pistol are fired at a target on the disk. The resulting motion of the disk validates the conservation of momentum laws but violates the expectations of the observer.
