... therefore has the same mass. The equal- arm balance gives us a way of comparing masses of objects of any kind, regardless of their shape, form, color, or what substance they are made of. 2. ... newtons, the usual units of force. As an example, we’ll find the weight of 1 kg mass on earth in both newtons and pounds: weight = mg = (1kg) (9. 8m/s 2 ) + 9. 8N = 2.2lb. (Adapte...
