To simulate this experiment, a ballbearing is aimed upwards at a suspended metal disc. When the ballbearing is shot, the disc is released. The ballbearing will hit the disc because their vertical acceleration is equal. | To simulate this experiment, a ballbearing is aimed upwards at a suspended metal disc.
