In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation. The rotation around a fixed axis of a three-dimensional body involves circular motion of its parts. The equations of motion describe the movement of the center of mass of a body.
on futuristic putters: Although there is a standard length for conventional putters (men's are 35 inches - 90cm, and women's are 33-34 inches - 84-86cm), don't be afraid of altering the length of your putter if you feel uncomfortable with it. Some putters are light and others are heavier.
What's Wrong -- Too Flat a Lie! If the putter length is too long, you either have the elbows crooked or the putterhead out away from you. Neither is good. The lie of the putter is determined by the height of your hands above the surface at address and by the horizontal distance from your hands out to the ball.
