2. Angular Momentum and Its Conservation Angular momentum is … L= I  Angular momentum is conserved…The total angular momentum of a rotating body, in a closed system, remains constant, if net torque is zero. I  I f  f See Example 8-16 See Holt Example 8-D (available online …control panel/Holt text)

3. Vector Nature of Angular Quantities  and L can be treated as vector quantities. We use the right-hand rule to determine the direction of these vector quantities. See page 230 for right hand rule.
