So, if the momentum vector points north and the radius vector points west, the angular momentum vector points straight up.

Moreover, the radial and tangential components of a vector relate to the radius of rotation of an object.

This function is a numerical computation of the average number of vectors that can be found within a sphere of radius r around a given vector.

As with Planar motion, the velocity is always tangential to the curve, but in this form can consist of different intermediate components that can now run along the radius and its normal vector.
