If the mass of an object increases, then will the acceleration decrease?

Please help. I'm kind of confused and it's for a lab report that is due soon.If the mass of an object increases, then will the acceleration decrease?
assuming density remains constant, then i believe yes, because that means an increase in surface area.If the mass of an object increases, then will the acceleration decrease?
Depends on the application:





If you are talking about linear momentum, then you have Newton's 2nd Law:





F = m * a


F = Force


m = mass


a = acceleration





So re-arranging this,


a = F / m , so as mass increases, acceleration decreases





In an example, forces can be air resistance or friction (which are constant), so throw a baseball, then throw a bowling ball... They both get the same forces acting on them, but the baseball has less mass, therefore it has higher acceleration than the bowling ball.
If the force remains constant, yes.
