Definitions

  • the present disclosure relates generally to golf equipment, and more particularly, to golf club heads with loft-based weights and methods to manufacture golf club heads.
  • initial velocity may affect the flight of the golf ball (i.e., ball flight).
  • club head shape and structure may affect the initial velocity, the spin rate, and/or the launch angle of the golf ball.
  • the initial velocity of the golf ball may be a function of the club head speed at impact between the club head and the golf ball. With all other factors held constant, a higher initial ball velocity may result in the golf ball traveling farther.
  • the physical geometry and structure of the club head may define a loft angle (e.g., club loft).
  • the loft angle may be an angle between a front end plane and a loft plane (e.g., a plane parallel to the club face).
  • spin may be imparted on the golf ball.
  • Ball flight and flight distance of the golf ball may vary based on the spin imparted by the club head. For example, a club head with a relatively higher loft angle may impart a relatively higher ball flight but may provide a relatively shorter flight distance. In contrast, a club head with a relatively lower loft angle may provide a relatively farther flight distance but impart a relatively lower ball flight.
