Angular Momentum and Its Conservation

Angular Momentum and Its Conservation. Angular momentum is … L= I w Angular momentum is conserved…The total angular momentum of a rotating body, in a closed system, remains constant, if net torque is zero. I w = I f w f See Example 8-16

Presentation Transcript

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

  2. Vector Nature of Angular Quantities • w,a, 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.

  3. Homework • P238 57,58,66,70,47a • Lab on Rotational Kinetic Energy and Angular Momentum Wed. • Test chapter 8 Thursday
