derive a relation between angular momentum n moment of inertia?
Anonymous:
L = I omega
need to derive L=I omega!?
Since angular momentum = mvr. .. substituting v = r omega we get as L = m r^2 w .... since we know that I = mr^2 ... thus L = I w
thanks buddy!

Remember that our angular momentum equation tells us thatangular momentum is moment of inertia multiplied by angular velocity. Since torque can change angularvelocity, and the amount of angular momentum an object has depends on its angular velocity, it makes sense that torque can change angular momentum.
