NEWTON’S SECOND LAW OF MOTION
Abstract
This study’s objectives are first to verify the direct proportionality of acceleration and net force if the mass of the body is constant and then to verify the inverse proportionality of acceleration and mass if the net force is constant. With the use of, mainly, the dynamics cart and the weight hanger, certain variables such as the mass on the cart and the mass on the hanger which is the net force were manipulated, controlled or changed in order to illustrate Newton’s second law of motion. However, through the process, some sources of error were expected that makes the results not a hundred percent accurate.
According Newton 's second law of motion, the behaviors of objects for which all existing forces are not balanced. The second law then states that the acceleration of an object is dependent upon two variables which are the net force acting upon the object and the mass of the object. By the moment that the forces become unbalanced, acceleration then exists. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. Therefore as the force acting upon an object is increased, the acceleration of the object is increased and so as the mass of an object is increased, the acceleration of the object is decreased.
Key Words: acceleration, net force, mass, Newton’s second law of motion
Introduction In order to formally state Newton 's second law of motion are as follows: the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. Through this, it can be observed that the emphasis has been on the net force. The acceleration is directly proportional to the net force; the net force equals mass times acceleration; the acceleration in the same direction as the net force; an acceleration is produced by a
