2D Angular momentum For rigid body pure rotation: L = I ω about pivot point O Conservation of angular momentum L i = L f Example Two identical small spheres, each with mass 0.2 Kg, are mounted on a 0.8 Kg slender rod. The 0.9 m long slender rod pivoted at its center rotates in a horizontal plane, and the spheres can slide along the rod. The slender rod
