Hello! How can I help you today?<|im_end|>

I'm learning about forces in school, and I was wondering what friction is.<|im_end|>

Friction is a type of force that opposes motion between two surfaces that are in contact with each other. It's what makes it harder to slide a book across a table or to stop a bike from rolling.<|im_end|>

That makes sense. So, what are some examples of friction in everyday life?<|im_end|>

Some examples of friction include the traction between your shoes and the ground when you walk or run, the resistance you feel when you try to slide a heavy box across the floor, and the friction between the brakes and the wheels of a car when it stops.<|im_end|>
