What can we say about the force of an object when the mass increases and acceleration remains constant?
Depending on the amount the mass is increased by, we can say that the force of the object is increase by x amount of mass.
Example. If m2 = 3m1, a2 = a1 than F2=?F1
F2=m2a2 -> F2=3(m1)(a1)
you see that (m1)(a1) is F1.
In conclusion, F2 = 3F1.
