Which statement is true because of newtons second law ?
a)when the net force on an object increases, the objects acceleration decreases
b)when the net force on an object decreases ,the objects acceleration increases
c)when the net force on an object decreases, the acceleration doesnt change
d)when the net force on an object decreases, the objects acceleration decreases

Newton's second law, by definition, states that,  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. Therefore, based on the given options above, the correct answer would be option D: when the net force on an object decreases, the objects acceleration decreases.
