Newton's 2nd Law
Newton’s 2nd Law states that, “Acceleration is produced when a force acts on a mass. The greater mass (of the object being accelerated) the greater amount of force needed (to accelerate the object).” (TeacherTech). In other words, more mass means more force to accelerate. When force is applied to an object it equals the mass times acceleration. (F=M*A). So relating this to tennis, if you want the ball to go really fast, you have to hit it with more force to increase its acceleration. When a racket hits a tennis ball, two main things happen. The tennis ball accelerates and the head of the racket decelerates. This is because the tennis ball has less mass, so it receives larger acceleration than the tennis racket. The acceleration of the tennis ball when it s hit by the racket is proportional to the force applied by the tennis player. So in simpler words, the harder you hit the further the tennis will go. Spiking the tennis ball also requires much force for the ball to accelerate. These are just a few examples of how Newton’s 2nd Law of Motion relates to tennis. The 3rd Law of Motion also applies to Tennis.
