Most forces are measured by newtons, named after Sir Isaac Newton a famous physicist and mathematician. Click here to learn more about him and his laws of physics.
Weight and Mass
Many people make mistakes and mix up the two measurements: mass and weight. Mass is the quantity of matter in an object and weight is the force that is acted upon an object due to the force of gravity. You see, there is a big difference. When people want to lose some of their body fat, they will say, "I want to lose weight." Technically, this is wrong because you can just go to the moon or climb to the top of Mount Everest to lose some weight. Scientifically, they should say, "I want to lose some mass."
Calculating the Force of Gravity
To measure how much an object weighs, first you must know how much mass the object has. It is better if you find the metric kilogram or grams instead of using imperial measurements (lbs, ounces, etc). Then, you simply multiply the amount of kilograms the object has by 9.8. Demonstrated in these formulas: Force = 9.8*Mass OR F= 9.8*m. To calculate the amount of newtons you should divide the amount of newtons by 9.8; shown in this formula: m=F/9.8
Scales
A spring scale is the easiest way to measure the amount of weight or mass the object has.
your scale should look like one of these:
It is very simple to use a spring scale to measure the weight of an object. You need to place the object onto the hook (tie a string around it if you cannot hook it), keep the scale steady and read how many newtons it weighs. You may also use it to measure the amount of friction the object creates by dragging it across a 180° surface. Make sure you keep a consistent pace!
