Ball lightning is a possible source of legends that describe luminous balls, such as the mythological Anchimayen from Argentinean and Chilean Mapuche culture.. According to statistical investigations in 1960, ball lightning had been seen by 5% of the population of the Earth.
Globe effect. The globe effect, also known as rolling ball effect, is an optical illusion which can occur with optical instruments used visually, in particular binoculars or telescopes. If such an instrument is rectilinear, or free of rectilinear distortion, some observers get the impression of an image rolling on a convex surface when the ...
Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body (such as a ball, tire, or wheel) rolls on a surface. It is mainly caused by non-elastic effects; that is, not all the energy needed for deformation (or movement) of the wheel, roadbed, etc., is recovered when the pressure is removed.
Gravity. Trajectory of a ball bouncing at an angle of 70° after impact without drag , with Stokes drag , and with Newton drag . The gravitational force is directed downwards and is equal to [4] where m is the mass of the ball, and g is the gravitational acceleration, which on Earth varies between 9.764 m/s 2 and 9.834 m/s2.

George Rhoads building a rolling ball sculpture. Rhoads created his first rolling ball machine in the late 1950s. [3] In the 1960s, Rhoads began experimenting with kinetic sound-producing metal sculptures. As he described these early machines, "You have a whole range of things happening in succession.
Rover is a plot device from the 1967 British television programme The Prisoner, and was a crucial tool used to keep 'prisoners' from escaping the Village. It was depicted as a floating white balloon that could coerce, and, if necessary, incapacitate or kill recalcitrant inhabitants of the Village. It also had the ability to subdivide.

The USBC and World Bowling promulgate bowling ball specifications. USBC specifications include physical requirements for weight (≤16 pounds (7.3 kg)), diameter (8.500 inches (21.59 cm)—8.595 inches (21.83 cm)), surface hardness, surface roughness, hole drilling limitations (example: a single balance hole including the thumb hole for "two-handed" bowlers [3]), balance, plug limitations, and ...
