Express angular momentum in terms of the rectangular components of linear momentum and position vectors.

Angular momentum is the rotational motion of a particle about a reference point. To express it in terms of rectangular components, we look at the position and linear momentum vectors of the particle. The position vector describes the location of the particle relative to the reference point, while the linear momentum vector describes the motion of the particle based on its mass and velocity. These vectors are decomposed into components along the x, y, and z axes.

Angular momentum is defined as the cross product of the position vector and the linear momentum vector. The resulting angular momentum vector has three components, one for each of the three spatial axes. These components depend on the perpendicular contributions of the position and momentum vectors along the other two axes.

For example, the angular momentum in the x-direction is generated by the components perpendicular to it along the y and z directions. In a similar fashion, the angular momentum in the y-direction comes from the contributions along the z and x directions, and so forth for the z-direction.

This method allows the rotational behavior of a particle to be analyzed in three-dimensional space, showing how different components of position and momentum contribute to the overall angular momentum.
