9) If mass is constant, but force increases, what will happen to the acceleration of the object? 10) If you increase the mass, but keep force constant, what will happen to the acceleration of the object?

9) If the mass is constant, but force increases the acceleration of the object will increase.

10) If you increase the mass, but keep force constant acceleration of the will decrease
