+Description :
+Newton's second law of motion pertains to the behavior of objects for which
+all existing forces are not balanced.
+The 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.
+The acceleration of an object depends directly
+upon the net force acting upon the object,
+and inversely upon 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.
