Golf ball

A small ball struck with golf clubs in the sport of golf. Its dimpled surface shapes airflow, helping control lift, drag, and flight.

Golf ball aerodynamics: The study of airflow and aerodynamic forces acting on a golf ball in flight. Explains how the ball’s surface and motion produce lift and drag.
Golf ball core: The central portion of a golf ball, commonly made from synthetic rubber or related polymers. Core composition and size influence compression and energy return.
Featherie: An early golf ball made from a leather pouch stuffed with tightly packed feathers. It was a prominent preindustrial design before molded gutta-percha balls.
Rules of Golf: The regulations governing how golf is played and how equipment may be used. The rules set technical requirements for conforming golf balls.
One-piece golf ball: A golf ball made from a single material, commonly used for practice or miniature golf. Its simple construction contrasts with layered balls designed for varied performance.
Magnus effect: A force on a spinning object moving through a fluid, caused by differences in pressure around it. Backspin creates aerodynamic lift on a struck golf ball through this effect.
Golf ball cover: The outer layer of a golf ball, made from materials such as urethane or ionomer. The cover affects durability, feel, and interaction with club grooves.
Guttie: A golf ball made from gutta-percha, a natural latex obtained from tropical trees. Its introduction made golf balls cheaper and easier to manufacture than featheries.
Golf ball fitting: The process of matching a golf ball’s performance characteristics to a player’s equipment and needs. Compression, spin, and flight can be compared to suit a golfer’s game.
Two-piece golf ball: A golf ball with a core and a separate outer cover. It contrasts with multilayer constructions that tune performance across different shots.
