Heres how it works. Lets say you and I have 2 yo yo's. you put yours down on the ground and roll it as hard as you can towards the finish line. I on the other hand throw my yo yo down and let it spin full speed for a full speed before I release it. Mine will have the greater momentum and therefore trap higher than yours even though you will have the quicker time with the lower trap speed. Take physics next semester. It should help you understand simple things like this. BTW I was not comparing AWD and 2WD.
