Newton's Second Law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
During class we demonstrated Newton's Second Law by rolling a chair in the hallway. We rolled the chair three different ways, with each starting at a gradual acceleration and a fast acceleration: the chair by itself, the chair with our partner, and the chair with a forty-five weight and our partner. At the end of the demonstration, we learned that when the force applied to the chair was increased, the acceleration of the chair was also increased; however, when we added our partner or our partner with the weight, the acceleration decreased because the mass had increased.
