Working principle for a ball bearing; red dots show direction of rotation. A four-point angular-contact ball bearing. A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It ...
Of the initial velocity, 13% is imparted to the fourth ball (which can be seen as a 3.3-degree movement if the fifth ball moves out 25 degrees) and there is a slight reverse velocity in the first three balls, the first ball having the largest at −7% of the initial velocity.
For example, a cartridge containing a 3 or 3 + 1 ⁄ 2-dram load of black powder was a common hunting field load, and a heavy full-power load would have contained about a 4 to 4 + 1 ⁄ 2-dram load, whereas a cartridge containing only a 2-dram load of black powder was a common target practice load. A hunter looking for a field or full-power ...

BB pistol with CO 2 cartridges and BBs. A BB gun is a type of air gun designed to shoot metallic spherical projectiles called BBs (not to be confused with similar-looking bearing balls), which are approximately the same size as BB-size lead birdshot used in shotguns (0.180 in or 4.6 mm in diameter).
