the friction against the matchstick and the rough surface produces enough heat energy to light up the matchstick and cause fire

When we rub a matchstick against the left side of a match box ,then friction between the head of matchstick and rough left side of matchbox produces heat. This heat burns the chemical present on the head of matchstick due to which the matchstick lights up.
The matchstick catches fire and starts burning. The burning of a matchstick would not be possible without friction.It is difficult to light a matchstick by striking it on the smooth surface because enough friction is not provided by a smooth surface to produce sufficient heat
