What name is given to the outward force on a rotating body?
Rotating reference frame completeness, the inertial acceleration formula_49 due to impressed external forces formula_50 can be determined from the total physical force in the inertial (non-rotating) frame (for example, force from physical interactions such as electromagnetic forces) using Newton's second law in the inertial frame: Newton's law in the rotating frame then becomes In other words, to handle the laws of motion in a rotating reference frame: In classical mechanics, centrifugal force is an outward force associated with rotation. Centrifugal force is one of several so-called pseudo-forces (also known as inertial forces), so named because, unlike real forces, they do not originate in
Rotating spheres for the sign change is that when ω > ω, the spheres actually are moving faster than the rotating observers measure, so they measure a tension in the string that actually is larger than they expect; hence, the fictitious force must increase the tension (point outward). When ω < ω, things are reversed so the fictitious force has to decrease the tension, and therefore has the opposite sign (points inward). The introduction of F allows the rotational observers and the inertial observers to agree on the tension in the string. However, we might ask: "Does this solution fit in with
