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.
