Ball speed refers to the velocity at which a ball travels after being hit, thrown, or kicked. It is an important measurement in various sports, including baseball, soccer, and tennis, as it can significantly impact the outcome of a game. Higher ball speeds can lead to more challenging plays for opponents and can enhance a player's performance. In sports like golf, ball speed is crucial for determining how far the ball will travel. Factors such as the player's technique, the type of equipment used, and environmental conditions can all influence ball speed. Coaches and athletes often analyze this metric to improve skills and strategies.
