WebApr 9, 2024 · Therefore, if the mass of an object is 1 kg which is falling with an acceleration of 9.8 ms⁻², the magnitude of the force will be given by-. F = ma. F = (1 kg) x (9.8 ms⁻²) F = (9.8 kg.ms⁻²) F = 9.8 N. Hence, it is clear that for an object with mass m= 1 kg, the weight of the object will be equal to 9.8 N.
