Displacement crossed with velocity?

[Maybe_Memorie]

I was reading Kleppner and Kolenkow's An Introduction to Mechanics, and in one of the problems you're given a force vector as a fuction of time. You're given initial conditions and asked to compute velocity and position, then asked to find the cross product of position and velocity, that is rXv.

Is there any physical significance of the quantity rXv?

Is there any physical significance of the quantity rXv?

Consider how the angular momentum of a particle is defined.
