Centrifugal G-force, represented as “G,” is a measure of the force experienced by an object in a centrifuge due to its circular motion. It depends on the centrifuge’s RPM (Revolutions Per Minute) and the rotor’s radius, calculated using the formula G = (RPM^2 * R) / 980, where G is the G-force and R is the radius in centimeters.
