# Newton’s second law is the acceleration of an object that is dependent upon two variables

Newton’s second law is the acceleration of an object that is dependent upon two variables. It is the net force acting upon the object and the mass object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of an object. As the force acts upon the object that has increased, the acceleration of the object will increase. As the mass of the object increases, the acceleration of the object will decrease. Newton’s second law is the equation of motion defining the field of dynamics. The equation is often used in physics. What does Newton’s second law mean in sports? In sports, Newton’s second law means the greater the force applied, the greater the acceleration. The more significant mass, the lower your acceleration will be.
A specific sport that Newton’s second law applies too is volleyball. The second law applies when a volleyball player spike’s the ball to their opponent’s court. In order to counteract the opponent’s defense, the volleyball needs to travel at a high velocity. This is where Newton’s second law comes into play, the greater the force the player applies on the ball, the greater the acceleration produced resulting in a higher velocity. As stated before the relationship between force and mass decides the acceleration outcome, this reasoning is why the volleyball is designed to have such a low mass. The low mass requires less force to produces a higher acceleration, which lowers the strain on the players muscles and joints. Since the arm need to generate the force to accelerate the ball, the lower mass helps reduce the excess force the arm needs to accomplish the same task. This reduction helps prevent injuries on the players joints and muscles.
