This document discusses the science project of Jaya Chandran on the sport of badminton. It notes that badminton involves 2 to 4 players using rackets to hit a ball back and forth. The document explains that friction is necessary for playing badminton, as there needs to be friction between the racket and ball for hits, between the palm and racket for gripping, and between the legs and ground for movement. The project was written by Jai.
