.01 101) 2 Moments of Inertia 01 s Second Law, the net force is equal to the mess of the object times the acceleration. The langer the mass, the smalier the acceleretion for mass i·traveling n, a carele o, radu Rhas a moment or inertia equal to MR, rme have an oegect that is not apont oemt ake a sold disk, me materw s derbied at "army of(starri When we talk about rotational motion, it not only how much mess there is but aso how it is distributed. The moment of inertia teils us how easy or hard it is to change the rotational spend of an object moment of inertia is d fferent than that for a point object and often needs to be calculated with a litee bt of calcus. The textbook of inertia for Rank the moment of inertia of the following objects. (-largest moment of inertia) 4 A point object with a mass of 1.5 kg traveling in a circle of radius 0.20 m 2A solid disk with a mass of 1.5 kg with a radius of 0.20 m spinning A solid sphere with a mass of 1.5 kg with a radius of 0.20 m spinning around its center Tries 2/10 Previous TriesExplanation / Answer
(a)
moment of inertia of particle I1 = m*r^2 = 1.5*0.2^2 = 0.06 kg m^2
moment of inertia of sphere about the center I2 = (2/5)*m*R^2 = (2/5)*1.5*0.2^2 = 0.024 kg m^2
moment of inertia of disk about the center I3 = (1/2)*m*R^2 = (1/2)*1.5*0.2^2 = 0.03 kg m^2
moment of inertia of hoop about the center I4 = m*R^2 = 1.5*0.2^2 = 0.06 kg m^2
