| Mar 17, 2021 at 6:24 | comment | added | Byte _ | Oh ok, that makes more sense. I guess I am specifically deriving the Work energy theorem then, not conservation of energy. I'll edit the post | |
| Mar 17, 2021 at 6:19 | comment | added | user87745 | Yes, you can derive the work-energy theorem but it is not the conservation of energy. What you are writing is not the general formula for conservation of energy, conservation of energy is precisely when that $\Delta W_{nc}$ is zero. What you are saying the equivalent of saying "being an omnivore is a generalization of being a vegan", it is just wrong. :) | |
| Mar 17, 2021 at 6:10 | comment | added | Byte _ | @DvijD.C. The general formula for conservation of energy I've seen is $U_i+KE_i+ΔW = U_f + KE_f$. I think without the $ΔW$ term it would truly be conservation of mech. energy, but I included a non-conservative force to get the $ΔW$ term in the final equation. If there's some nuance I'm missing I could edit it out. The non-conservative force isn't important to my question. | |

| Mar 17, 2021 at 5:52 | comment | added | user87745 | I haven't looked at your calculations but why do you think this is the conservation of mechanical energy? Mechanical energy is not conserved when you have non-conservative forces. | |
