A bicycle is traveling North. The direction of the angular momentum vector of it's front wheel is?
I chose "North." The answer is West. Why?
thanks

Angular momentum vector is a physical quantity that describes the rotational motion of an object. It is a vector quantity that has both magnitude and direction.
Angular momentum vector is calculated by multiplying the moment of inertia of an object by its angular velocity. The formula for angular momentum vector is L = Iω, where L is the angular momentum, I is the moment of inertia, and ω is the angular velocity.
The main difference between angular momentum vector and linear momentum vector is that angular momentum describes rotational motion, while linear momentum describes linear motion. Angular momentum is also a vector quantity, while linear momentum is a scalar quantity.
Yes, angular momentum vector can change if there is a change in the moment of inertia or the angular velocity of an object. This change can be caused by external forces, such as torque, acting on the object.
Some real-life examples of angular momentum vector include the spinning of a top, the rotation of a planet around its axis, and the movement of a spinning figure skater. These all involve objects with a non-zero moment of inertia rotating around a fixed axis.
