How Friction Works.
Friction is a force that slows things down and creates heat. In a car there is oil to help prevent objects (such as an engine) from overheating. This is called lubrication.
Friction makes things slow down and heat up. For example: when you are riding on your scooter and you stop pushing, friction is what makes you slow down. If you weren't wearing shoes and you put your foot on the brake, your feet would burn because of the friction of the brake and the wheel rubbing together.
What would happen if friction didn't exist? Firstly, if a car was driving on the motorway and it suddenly needs to stop, it won't be able to because friction wont be there to help it slow down. Basically friction is a big part of the world.
Oil can make friction less powerful, that is why you find alot of oil in motor vechiles. Using oil for that purpose is called lubrication. Lubrication helps alot in these senarios; to stp cars from overheating and to help things move smoothly. If an object has certain edges on its surface the oil will run on them and they will work better.
Friction helps in everday life. It works with gravity and lubrication to reduce the dangerous circumstances of itself. Overall, you could say friction is an important facet of our lifes.
