Physics is like the rules of a big playground called the universe. Just like how you have rules for playing games, physics has rules for how things move and work. For example, when you throw a ball, it flies through the air and comes back down because of a rule called gravity. Gravity is like an invisible friend that pulls things down to the ground.
Think of physics as a magical toolbox full of special tools that help us understand how everything works. There’s a tool called light that helps us see things, and another tool called sound that lets us hear. When you clap your hands, the sound is like tiny waves traveling through the air to your ears.
Physics is also like a magic show that explains why things happen. When you see a rainbow in the sky, it’s because light is bending and splitting into different colors, like a magic trick. And when you ride a bike, physics helps you balance and move forward. It’s like having a secret helper that makes sure everything in the world works just right.
