Document Summary
0. 25n: 0-5 n scale is better to use then the 0-20 because if you use a very strong scale to lift a light weigh like 3. 0n. It will not give a measurement because the weight is too light. While you are dragging the scale on the slide, the scale will point of lots of numbers but you do not know which one to choose. However, sometimes when the object slides on the board the friction makes the object to have a greater force. 5n: the weight will also increase, fg = (9. 8 n/1 kg) (mass) + 0. Force of gravity equals 9. 8n divided by 1 kilogram times mass plus zero. On earth, the ratio of weight to mass is 9. 8. You can hook the weight then make a horizontal slide and then slide the spring scale and you can still get the measurement.
