Angular Momentum - 2
L = I 
The angular velocity
and the angular momentum L are both vectors! The
vector lies along the axis of rotation and points toward one end
or the other according to the "right hand rule":
Rght Hand Rule
Just as we wrote
for the linear case, we can also write
for the rotational equivalent.
Remember, torque is a vector. When we wrote
or
r and F are vectors and their "cross product" or "vector product" is also a vector!
