Friction isn't a size. You can increase friction by increasing the pressure on two objects as they pass, or reduce lubrication between them.
To increase friction, you can increase the weight pressing the surfaces together, roughen the surfaces in contact, or use a material with higher friction properties.
An example of unuseful friction is when trying to push a heavy object on a rough surface where the friction makes it difficult to move the object smoothly.
The force that makes it hard to pull the box is friction. Friction is a force that opposes the motion of objects sliding against each other.
The force that makes bicycle brakes work is friction. When the brake pads press against the wheel rim or disc, friction is created, which slows down the rotation of the wheel and ultimately stops the bike.
A simple example of fluid friction is when you stir a spoon in a cup of honey. The honey resists the motion of the spoon, creating friction that makes it harder to stir.

It is the friction between the snowboard and the snow that makes it slow down.
No it makes your butt bigger :D

it makes it bigger because your fat
usually when you rub on to something it creates heat so that makes friction. Ice has no friction because it slips
Oil is used to reduce friction.
Friction doesnt not depend on the surface area...but the force of friction does! We cannot change the friction of a material but we can change the force due to that friction on another material in contact with it. Using this concept, racing cars have bigger tires to minimise the force of friction acting on them. They cannot change the friction of the road, so they change the resultant force on the tires.
