However, through the process, some sources of error were expected hat 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 net force. The NET FORCE: the net force is the vector sum of all the forces. If all the individual forces acting upon an object are known, then the net force can be determined. A = Fine/ m or often and more familiarly rearranged to: Fine=m a To explain the law further, First, it states that if you place a force on an object, it will accelerate or change TTS velocity, and it will change in the direction of the force.

So, a force aimed in a positive direction will create a positive change in velocity which is a positive acceleration. And a force aimed in a negative direction will create a negative change in velocity which is then a negative acceleration. Simply put, it accelerates in the direction that you push it.

Second, acceleration is directly proportional to the force. So basically, suppose you are pushing on an object, causing it to accelerate, and then you push, say, three times harder, the acceleration will be three times greater. Third and lastly, acceleration is inversely proportional to the mass of the object.

Therefore principally, if you are pushing equally on two objects and one of the objects has five times more mass than the other, it will accelerate at one fifth the acceleration of the other.
