Definition Weight
Weight tells us how heavy something is. Imagine you have a teddy bear and a big book. The teddy bear feels light when you pick it up, but the book feels heavy. That’s because the book has more weight than the teddy bear!
Definition Balance Scale
A balance scale is a tool we use to compare the weight of two things. It has two sides that go up or down. If one thing is heavier, its side goes down, and the lighter side goes up.
Weight Units
We can measure weight using different objects like marbles or candies. But these objects are not the same for everyone. Your friend might have bigger marbles than yours, making it hard to compare. To solve this, mathematicians created universal units called grams and kilograms, so everyone can measure and compare weights the same way.
Definition Units of Weight
- Gram \(\left(\mathrm{g}\right)\): A small unit of weight, about the weight of a small candy.
- Kilogram \(\left(\mathrm{kg}\right)\): A bigger unit of weight, about the weight of a big book.
