This may not be the conventional way of serving a tennis ball but it’s a great application of conservation of momentum. As the ball and racket rebound off the ground, the racket transfers some of its momentum to the ball. This launches the ball high enough to allow the tennis player to deliver the serve. Give it a try – but don’t use an expensive racket!
