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??
