According to newton's second law of motion, when the net force on an object is greater than 0 how is its mass related to its acceleration? A. They are directly related
B. They are not related at all
C. They are equal
D. They are inversely related

C. They are inversely related

Newton's second law is as follows:

Where is the net force
is the mass, and is the acceleration.
We can rewrite that same law as follows:

where we can see that mass and acceleration are inversely related.
For a definite force value, greater than 0 as the problem mentions, if the mass increases, the acceleration will decrease, and vice versa.
