What is a Weight?
Definition Weight
Weight tells us how heavy something is. When we compare two objects, the heavier one has more weight and the lighter one has less weight. For example, a big book is heavier than a teddy bear.
Definition Balance Scale
A balance scale is a tool used to compare or measure the weight of two objects. It has two sides. The heavier side goes down and the lighter side goes up. If both sides are level, the two objects have the same weight.
Weight Units
We could use marbles to measure weight, but what if your marbles are bigger than your friend's marbles? You would get different answers! To make sure everyone's measurements are the same, we use standard units. The standard units for weight are the gram and the kilogram.
Definition Units of Weight
- Gram (\(\mathrm{g}\)) — A small unit of weight. We use grams to weigh light objects, like a small candy or a paper clip.
- Kilogram (\(\mathrm{kg}\)) — A bigger unit of weight. We use kilograms to weigh heavier objects, like a big book or a school bag.
