Thanks for the reply. I've just looked through that section, and it seem that omega x v (eq. 1.5-13) is a recurring theme in dynamics modelling. After doing unit analysis, I found that it gives acceleration. So I guess I will try making use of it in my own equations of motion. Another thing

Hello all, As part of a project at school, I have been trying to come up with equations of motion for an aerial platform, so that I may use the equations to design a control system. The issue is that I'm having trouble coupling linear and angular dynamics. Specifically, I need to describe the
