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.
Ask players which putt scares them the most at Augusta, which putt is so fast that they're afraid to even pull the putter back, and you'll get an assortment of answers: above the hole on No. 2; from the wrong tier on Nos. 6, 9, 14, 16 and 17; and any putt on No.5. Every other hole also got a mention. But not all of the putts are fast.
