Friction is a force that opposes the motion of objects sliding against each other. Think of it as nature's way of throwing a little resistance into the mix to keep things interesting. For instance, if you've ever tried to push a heavy box across a carpet, that stubbornness you encounter is all thanks to friction putting up a little fight! In the real world, Newton's First Law can be seen in action when you're riding a skateboard. If you roll down a hill and suddenly hit a bump, your body tends to keep moving forward due to inertia, even though the board stops! This is why it's crucial to wear a helmet—your body’s natural tendencies could lead to a rather abrupt stop if you're not careful!
