How is acceleration affected if you apply the same force to two objects of different masses?

F=M(A), you can simply derive a formula by solving for A. So devide F by M and you get A=F/M. Then you can ask yourself, if when you increase of decrease mass what will happen to acceleration. assuming the unbalanced force is constant. soo when mass increases acceleration decreases. and when you take away mass from a body, then you can say that acceleration increases. You must assume that the force is constant. :D
