Abstract
A golf ball can include a core, mid layer, and a cover. The golf ball can satisfy the following mathematical formulas (1) and (2), Fw / Fwn ≤ 0.98 Fw / Fwn 2 / Fp / Fpn ≤ 0.98 , wherein Fw represents a maximum vertical force of the golf ball measured under a first condition, Fwn represents a maximum vertical force of a standard ball measured under the first condition, Fp represents a maximum vertical force of the golf ball measured under a second condition, and Fpn represents a maximum vertical force of the standard ball measured under the second condition.
