Friction is the force that opposes motion between two surfaces that are in contact with each other. It is caused by irregularities on the surfaces that come into contact, which lock together and resist sliding past one another.
There are two types of friction: static and kinetic. Static friction occurs when two surfaces are not moving relative to each other, and prevents them from starting to move. Kinetic friction occurs when two surfaces are moving relative to each other, and slows down or stops the movement.
Friction plays a major role in our daily lives, from the tires on our cars to the soles of our shoes. It can be both helpful and harmful depending on the situation. For example, friction between the tires of a car and the road helps the car accelerate and stop, but too much friction can lead to tire wear and reduced fuel efficiency.
