我地而家就學緊Force
不過我學到好亂
佢話:The weight of an object is the force of gravity pulling it towards the Earth. We can use a spring balance to measure weight. Since weight is a force, it is measured in newtons.
跟住佢話仲有樣野叫做mass
佢仲話:The mass of an object is the amount of matter in it. Mass is measured in kilograms (kg) or grams (g). As the amount of matter in an object remains the same in all places.
咁我想知要點樣分果樣野係唔係mass
個unit係用newton定kg
(請大家唔好見我成段課文係英文就答英文,請用中文作答)
希望大家幫下手啦
