The angular velocity vector of rotation points in the direction determined by the right-hand rule. Here's how it works:

1. Curl your fingers in the direction of the rotation.

2. Your thumb will point in the direction of the angular velocity vector.

Example:

* If a wheel is rotating clockwise as viewed from above, your fingers would curl clockwise. Your thumb would then point downwards, indicating the direction of the angular velocity vector.

Key Points:

* Angular velocity is a vector quantity, meaning it has both magnitude (speed of rotation) and direction.

* The direction of the angular velocity vector is perpendicular to the plane of rotation.

* The right-hand rule is a standard convention used in physics to determine the direction of vector quantities related to rotation.
