Inertia equals mass times radius squared
WebRotational inertia is given the symbol I I. For a single body such as the tennis ball of mass m m (shown in Figure 1), rotating at radius r r from the axis of rotation the rotational inertia is I = mr^2 I = mr2 and consequently … WebIncreasing the mass or decreasing the radius increases the centrifugal force in direct or inverse proportion, respectively, but increasing the speed of rotation increases it in proportion to the square of the speed; that is, …
