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.
For a belly putter, take your stance with a standard putter and have an assistant measure from the butt end of the putter to your desired anchor point. Add this distance to the shaft's length to get the correct belly putter length.For a long putter, take a comfortable, more upright stance, and have an assistant measure from your anchor point to the ball.f you're 6 feet 2 or taller, use a belly putter with a shaft length between 45 and 47 inches. Use a 41- to 44-inch putter if you're 5 feet 9 to 6 feet 1 tall. If you're 5 feet 8 or shorter, the correct length is between 38 1/2 inches and 40 inches.
