un día sin fricción

Abstract

What would you do if one day you wake up and you realize that friction, for some strange reason, exists no more? What would it happen? How would you develop your day? Would it be better or worse? What it is certain is that strange things would happen in every aspect of our lives, or even it would be impossible to do almost all every day activities where friction is involved sometimes without realizing it, as getting dressed, using everyday objects or devices, machinery and vehicles, all would work in different manner. Despite not being a fundamental force (the four fundamental forces are gravitational, electromagnetic, weak nuclear and strong nuclear), it is essential to the functioning of almost everything. © Universidad Nacional Autónoma de México.
