If you increase the mass of an object, but keep the force on it constant, its acceleration decreases? true or false

(2) Answers

That statement is true. Prof Newton said:        Force = (mass) x (acceleration) -- If the force is constant, then the right side of the equation must be constant too. -- The right side of the equation is the product                                                (mass) x (acceleration) . -- If either of those changes, then in order to keep the product constant, the other one has to change in the opposite direction. -- So if the mass increases, then the acceleration decreases.


it really depends. On a hill, the object would increase speeds. Flat terrain, it would slow.
