Angular Momentum - 2
Angular momentum = (rotational mass) x (angular velocity)
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
r and F are vectors and their "cross product" or "vector product" is also a vector!
