RP-2 If you are able, try moving your right hand in a circular motion, as if cleaning a table. Then start your right foot doing the same motion, synchronized with your hand. Now reverse the right foot’s motion, but not the hand’s. Finally, try moving the left foot opposite to the right hand.

a. Why is reversing the right foot’s motion so hard?

b. Why is it easier to move the left foot opposite to the right hand?
