Nascar races tend to use left turns. Why is this?
Well my reasoning behind this would be that when an object (like a wheel) rotates counter-clockwise, it generates torque in a direction perpendicular to its rotational plane. This torque points to the left, therefore left turns are easier than right turns when driving forward.
Now I ask you, Physics Forums, why does r×F produce a leftward torque when the object is rotating counter-clockwise? Why not rightward or some other direction? Does it have something to do with particle spin?
