## 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??
