Multiple Choice

The law of centrifugal force states that a spinning object will pull away from its center point and that the faster it spins, the ____ the centrifugal force becomes.

The outward effect you feel in a spinning system grows as speed increases. In circular motion, the inward force needed to keep the path is F_in = m v^2 / r. In a rotating frame, this outward effect is described as the centrifugal force, with magnitude F_cf = m v^2 / r (or m ω^2 r). So as speed goes up (v increases, or ω increases at a given radius), F_cf increases proportional to v^2 (or ω^2). That means faster spins produce a stronger outward tendency. An intuitive picture is water in a spinning bucket or a tetherball pulling harder outward as you whirl it faster. In an inertial frame, there isn’t a real outward force; the effect comes from inertia and the required inward centripetal force. But in the rotating-frame view used here, increasing speed makes the centrifugal force larger.
