-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.
