In this case, the force applied by the player and the racquet is the only force acting on the birdie therefore Fnet is equal to the force applied. Therefore if you double the force applied to the birdie, the speed at which the birdie accelerates at will also be doubled. Newton's 3rd Law Law: For every action there is an equal and opposite reaction.

Principle Operation Ball Miller Machine
Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.
