Relative velocity of rigid link summary

The video tutorial explains the concept of angular velocity, denoted as Omega, and its application to a rigid body with two points, A and B. It describes the relationship between the velocities of these points, VA and VB, and the relative velocity VAB. The tutorial simplifies the velocity formula using the constant distance R between A and B. It further explains that from point B's perspective, point A moves in a circular path, leading to the conclusion that the magnitude of VAB is R Omega. The video also covers the units of angular velocity in radians per second and clarifies the concept of relative velocity.

What is the formula for the magnitude of VAB in terms of R and Omega?

Define Omega in the context of angular velocity.
