| May 26, 2022 at 18:02 | comment | added | Due.Berto | @ACuriousMind I am sorry, I didn't mean that we defined work as it is after knowing all of the fundamental forces; I tought this could be an explanation of why (at least in classical mechanics) this model works: to move a box (in the void) with a constant force over 1 meter I have to move exactly at the same velocity of the box over the same distance, or the forces between the particles of my hand and those of the box will decrease. Because of your 2nd point, however, my "idea" doesn't make any sense, and I thank you for the answer. | |

When metal balls are dropped into sand, the penitration depth, $p \propto v^2$ one could theorise that the a qauntity called kinetic energy is therefore proportional to v^2, kinetic energy is a useful qauntity to define, that relates forces to distance (/velocity). I'm sure if you type in "Émilie du Châtelet kinetic energy" you will be able to piece together why kinetic energy is defined the way it is and the experiments that led to its conception. | |

| May 26, 2022 at 16:33 | comment | added | ACuriousMind♦ | 1. The definition of "work" is much older than our understanding of the fundamental forces, so I'm puzzled how you think the two could be related. 2. "It's also known that the four fundamental interactions are distance-depending forces." - at the very least for the weak "force", I have trouble determining in what way you think this "is known" (obligatory xkcd). 3.
