Homework Statement



give equations for angular momentum in terms of :
1. angular velocity
2. a point mass moving along the circumfrence of a circle with a tangential (linear) speed v.

Homework Equations



none

The Attempt at a Solution



1. is L= I w...angular vel = moment of inertia X angular velocity

2. I = mr^2


im not too sure about the second one? can someone help??

The second one is moment of inertia, not angular momentum. For the second one, just go back to the definition of angular momentum.
