What is friction?

Friction is what makes it harder to slide things across a surface, like when you try to push your toy car across the floor.

Imagine you're trying to move a big block on the floor. It doesn’t want to go easily, that’s friction working against you! Friction happens because the tiny bits of the block and the floor are touching each other, like a rough handshake between two surfaces.

If you push your toy car across a smooth table, it moves more easily than if you push it on a carpet. That’s because smooth surfaces have less friction than rough ones. It's like sliding on ice versus trying to slide on a bumpy road, one is smoother and easier!

Friction happens when two things touch and move past each other. The more they grab onto each other, the harder it is to move them. So if you rub your hands together really fast, they feel warm, that’s friction doing its thing!

You can feel friction every day when you walk, ride a bike, or even when you open a door. It's not magic, just something that helps things stay in place or makes moving things a little harder.
