Physics - Mechanics - Rotational Motion - Moment of inertia - Moment of Inertia

A 5-step lesson. Step 1: 'Moment of inertia (I) measures resistance to rotational acceleration, just as mass measures resistance to linear acceleration. τ = Iα (compare to F = ma).' Step 2: 'For a point mass: I = mr² (mass × distance from axis squared). Mass farther from axis = larger I.' Step 3: 'F
