Moment of Inertia and Rotational Dynamics

ROTATIONAL DYNAMICS
Newton’s Rotational 2nd Law of Motion	Moment of Inertia
∑τ = Iα	I = ∑mr²

MOMENT OF INERTIA
Rod rotating about its center I = 1/12 ML²
Rod rotating about one end I = ⅓ ML²
Solid Sphere I = 2/5 MR²
Thin Sperical Shell I = ⅔ MR²
Solid Cylinder / Disk I = ½ MR²
Hollow Cylinder I = MR²
