Hello everyone !
About one year ago I read a book called "Insoluble mais vrai" which is a popular science book.
In one chapter, the author , David Louapre, wrote :
"Sauf qu'il faut se souvenir qu'en physique, le mouvement naturel des corps les conduit à minimiser leur énergie."
Translated in english :
" Remember that in physics, objects' natural motion tends to minimize their energy."
It didn't disturbed me up to now. But I'm not quite sure that I understand the sentence. Yes, when you throw something and it's free falling, it minimzes its energy until reaching the ground or something else. But is there a demonstration of that principle and above all, why ? Why objects minize their energy ?
Thanks in advance.
Hugo
