A golf ball including a piezoelectric material allows the characteristics of the golf ball to be changed by application of an electric current. An electric current may be applied to the piezoelectric material prior to impact of the golf ball by the golf club using a golf tee with a power source. An electric current may be applied to the piezoelectric material after impact of the golf ball by the golf club and during flight of the golf ball. By selectively applying or removing electric current prior to, during, or after impact with the golf club, the characteristics of the golf ball may be changed and the flight path characteristics of the golf ball may be altered.
