When a fire stone is rubbed on a hard and
rough surface, we get fire. This is because of friction.
The friction is caused because of the warmth generated due to the rubbing action. The intensity of friction produced is directly proportional to the roughness of the surfaces being rubbed together. In other words, as the surface roughness increases, the friction produced is also enhanced. In turn, the heat generated also increases.
