Hello Esra
Friction is the force that tries to stop things from sliding or moving past each other. Imagine rubbing your hands together—they get warm, right? That warmth is caused by friction. It's always there when two surfaces touch and one tries to move.
When you walk on the ground, it's the friction between your shoes and the floor that helps you move forward. Without friction, you'd slip like on ice!
