What are physical laws?

Physical laws are like rules that everything in the universe follows, just like how you follow rules at recess or during a game.

Imagine you and your friends have a special playground where everyone has to follow certain rules. For example, if you push someone on the swings, they always go higher, no matter who pushes them. That’s like a physical law! It's something that happens every time, without fail.

Another rule might be that when you jump up, you always come back down. No one stays floating in the air forever. That’s because of gravity, another kind of physical law. Gravity is like an invisible hand that pulls things toward Earth, just like how a friend might gently pull you back to the ground after you leap.

These rules are always there, even when no one is watching. They work for big things like planets and small things like toys, everything follows them! Physical laws are like rules that everything in the universe follows, just like how you follow rules at recess or during a game.
