If you use the same force on a less massive object what happens to the acceleration

Acceleration = Force/Mass

If F= 20N , M = 10KG , then A will be 2m/s^2

Now, if we use Same 20N force on 5kg mass, ,Then A will be 4m/s^2.
Therefore Acceleration will increase if u use same for on less massive objects

During the 1800s. hope this !

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
