LIGHT BY FRICTION

Here comes my observation, a matchstick can produce heat by rubbing, and the heat will automatically

create a light.

But then, there is something that I realized, there was a force that is exerted on the matchstick. And the

question is, what kind of force is this?

Come to think of it, heat was produce by simple rubbing and this is what we called frictions. Frictional

force or simple friction is the force that resists the movement of one object over another object

resulting in heat.

Another example for this is when you are cold, and try to rub your palm. It can produce heat, and also

when we are walking of course, without friction, we cannot maintain our balance. We have the

tendency to slide when we are trying to walk.

To sum it up without friction there would be a chaotic world. Because friction is the producer of heat

that will led to light.
