... If you apply the same force to several different objects, the one with the most mass will have the smallest acceleration and the one with the least mass will have the greatest acceleration. One unit of force causes a 1-kg mass to accelerate at 1 m/s2, so one force unit has the dimensions 1 kg·m/s2 o ...
