When we say something is heavy, it means it takes a lot of effort to pick it up. Imagine you have a big bag of your favorite toys. If the bag is full of toys, it might be hard to lift because it’s heavy. But if the bag only has a few toys, it feels much lighter and easier to carry.

Think of a big elephant and a small mouse. The elephant is much heavier than the mouse. The elephant needs strong legs to walk because it carries a lot of weight. The mouse, being light, can run around quickly and easily.

Another way to think about it is like when you try to push a door open. If it’s a big, thick door, it feels heavy to push. But if the door is thin and small, it’s much easier to move. So, heavy things require more strength and effort to move, while light things are easier to handle.

Imagine holding a big rock versus holding a small feather. The rock feels heavy in your hands, while the feather is so light, it might even float away in the wind. This is how we understand the idea of heavy.
