The Physics of Smash Factor

In golf, Smash Factor measures how efficiently you transfer the energy from the clubhead into the golf ball. The formula is simply: Ball Speed รท Club Speed.

Because the USGA limits the trampoline effect of golf clubs, the absolute maximum theoretical Smash Factor for a Driver is 1.50.

Different clubs have different limits. A 7-iron has a higher loft, meaning more of the energy goes into creating spin and height rather than forward velocity. Therefore, a perfect dead-center strike with a 7-iron yields a Smash Factor closer to 1.33.

To maximize your distance, you don't necessarily have to swing out of your shoes. Finding the center of the face (100% Impact Efficiency) to maximize your Smash Factor will often yield better distance than a faster, off-center swing.
