The Effect of the Striking Implement's Diameter on a Ball's Rebound Height and Area of Contact.
Kirby, Ronald F.
The primary purpose of this study was to determine what effect the diameter of the striking implement has on a basketball's rebound height and on the area of contact between the ball and the implement. A secondary purpose was to determine if changing the air pressure of the ball would alter the pattern established with standard pressure. A basketball was dropped repeatedly from a height of 100 inches above the floor onto one of three striking implements of different sizes located five inches above the floor. The mean rebound height and the mean area of contact produced by each striking implement and for each pressure was computed. Results indicated that (a) the diameter of the striking implement was a significant factor in how high the basketball rebounded, (b) the diameter of the striking implement was a significant factor in the size of the contact area, (c) the smaller striking implement produced the greatest rebound height and the least area of contact, and (d) there is an optimum implement diameter for the specific amount of force and the coefficients of restitution for the ball-implements used in this study.
