Answer: A decrease in acceleration causes the mass to increase.
Explanation:
Let's rewrite this as:
"For a constant force F, we can see that heavier objects accelerate less"
Then, as the mass increases, the acceleration of the object decreases.
This is known as an inverse relationship between acceleration and mass.
By second Newton's law we have that:
F = m*a
Force equals mass times acceleration.
So if the force is constant, we can write it as:
a = F/m.
In this equation, we can see that, if the acceleration decreases and F remains constant, then the mass m must increase (because it is in the denominator)
Then the correct option is:
A decrease in acceleration causes the mass to increase.
