In a tennis match, when a moving tennis ball is hit by a tennis racket, then the  direction of the tennis ball changes and it goes in a different direction. In this case,the force exerted by the tennis player's racket changes the direction of the moving ball as we know that force changes the direction of a moving body. And the ball buldges for a very short time towards the ends on hitting by the racket.
