Throughout a set of golf clubs there are various lofts and lengths of clubs. These lofts and lengths serve a purpose to create either a more vertical force applied to the ball or a more horizontal force. For instance a club with more loft is designed to contact more below the equator of the ball providing a more vertical force resulting in a higher launch angle than a less lofted club that is designed to contact closer to the equator of the ball to provide a more horizontal force resulting in a lower launch angle. Additionally the length of the club dictates the angle the club is swung on by putting the golfer farther away from the ball with a longer club and closer to it with a shorter one, This in turn dictates that the longer club delivers more horizontal forces and the shorter one more vertical forces. If you think about the least lofted club intended to get the ball in the air, the driver it also has the longest shaft. Both these elements will produce horizontal forces resulting forces being delivered close to the equator of the ball resulting in the need of a tee for the ball to be used to get the ball airborne. At the other end of the scale we have the most lofted clubs with the shortest shafts both elements producing vertical forces resulting in a high short ball flight.
