| S.I. Base Unit of Mass=Kg => 1 Kg =9.81 N( Because F=ma Here for free fall a=g=9.81 so, F=mg=1*9.81=9.81 Newton). Force=Newton (N). Energy=joule(J)=>Kg x m^2 / s^2 ( So here Also can Used 9.8 Because its related to Kg). Power = Watt(W) =>Kg x m^2 / s^3 (So here Also can Used 9.8 Because its related to Kg). |
