Smash factor represents the efficiency of energy transfer from the club head to the golf ball at impact. It is calculated by dividing ball speed by club head speed. A higher number indicates a more efficient transfer of energy, resulting in greater distance. For instance, if a golfer generates a club head speed of 100 mph and the resulting ball speed is 150 mph, the calculation yields a factor of 1.5.
This metric is valuable in understanding and improving a golfer’s swing and equipment setup. It highlights how effectively a player is using their club head speed to generate ball speed. Historically, golfers and club fitters have used this ratio, along with other data points like launch angle and spin rate, to optimize club selection and swing mechanics. Improving efficiency in energy transfer can lead to increased distance and improved accuracy.
