A topspin serve in tennis is a serve where the player imparts forward spin on the ball, causing it to rotate forward as it travels over the net. This causes the ball to drop quickly and bounce higher when it lands, making it harder for the opponent to return. It is an effective serve for generating power and control.
Sports where you serve a ball include tennis, volleyball, badminton, table tennis, and pickleball. In tennis, the serve starts each point, while in volleyball, the serve initiates play and is crucial for scoring. Badminton and table tennis also require a serve to start each rally, and in pickleball, the serve is used to begin each point as well.
