In this picture, cars are driving down a street and are looking for a parking space. What many of these drivers don’t know is the friction that is occurring right before their eyes. In order for the cars to move, they need friction between the ground and the tires. The grooves in the tires mesh with the grooves in the street, which help propel the car forward. Without friction, all of the cars would be sliding instead of rolling.
Even though friction opposes motion, it isn’t strong enough to stop all motion. That’s why cars can move. So the next time you go driving, don’t forget about friction that’s moving you.
