But I thought the units of acceleration were m/s2 a good question. N/Kg is a funny unit for That’s acceleration this is actually the same as m/s2. isn’t it, but have a look at why by putting in the units on our Let’s equation below: acceleration = Force / mass T his is the same as saying: acceleration = (mass x acceleration) / mass Now put in some units into the second equation: let’s acceleration = Kg x m/s2 Kg We can then simplify this equation by removing Kg. acceleration = Kg x m/s2 Kg This leaves us with the units for acceleration, m/s2 acceleration = m/s2
