Spring balance is used to determine the force acting on the object (weight). A balance determines mass by balancing an unknown mass against a known mass. In simple terms, a balances measure mass, while scales measure weight. Spring scales can be configured to display force (in Newtons) or weight (in g/kg), or both side by side; technically, only the former reading is accurate, since the weight is actually a representation of how much force it exerts on the spring thanks to the gravitational pull on the mass of the object (incidentally, this is also why the weight of an object is different on other celestial bodies, even though it has the same … 1.0 out of 5 stars 2 ₹199 ₹ 199 ₹260 ₹260 Save ₹61 (23%) Save extra with Cashback.
