Friction

This one is an absolute gem... Just try to imagine to this..... Amazing, isn't it? For all those who don't know what friction is, it is the force which stops moving objects when they rub against another object. This friction is pivotal in stopping vehicles. If not for it, all objects would be perpetual motion.
Just taking one step would mean that one would never be able to stop....!! Some people have said that machines will be come very efficient with no wastage of energy, but friction is the force that is so important that we would not have been able to progress a little bit without it......
The amazing part is that one will need rocket packs to stop moving, that too, in the opposite direction in which one is moving.... Usually, in our world, we need rocket packs to go quick, isn't it? Well, just one jump would take you to outer space!!! It would be one small step from you, but a giant leap as well!
Leaving the jokes aside, I would seriously like to ask you if you confidently think that you can live a usual life without friction? Yeah, I do hope that this post evoked some thoughts in you. Watch this space for more.....
