Conventional golf balls are engineered according to aerodynamic specifications, basically to perform in flight. These balls are not suitable for the terrain of the grass. No consideration has been given to make conventional golf balls putting compatible. Conventional balls are aerodynamic and the improved golf ball for putting, presented in this invention, is a "Terradynamic Ball". This invention provides a ball engineered primarily for putting and is accomplished by giving the ball more inertia and power and by decreasing friction and resistance. It is designed according to the Laws of Motion, which states that, "Every body continues in its state of rest, or motion in a straight line, unless it is compelled by some external force to change that state". This "Terradynamic Ball" comprises a heavy metal core, to provide greater inertia, and a lower center of mass, and a cover whose outer surface is uniformly even and smooth, minimizing friction rolling over grass. These factors, working together, in combination, develope greater stability in the rolling ball, and, consequently, create a greater accuracy in putting.
