of course sir i want to learn physics
but my dad & mom insisted on learning medicine instead
then please the first three papers means nothing to me
please check the last four papers
please give me a chance
the first three papers i was sure 90% that they are wrong
but the last four papers really they are good & better than the first three ones
You know, biology, chemistry (which underly medicine) are all ultimately physics. You can easily study medicine and physics, but just as you would not perform surgery to learn how it works, you have to study the physics before you construct your own proofs.
This website, is an AMAZING resource of educational material. This is just a suggestion, because although this is against the grain for me, usually, I get the sense that you really want to learn, and believe this is the best way.
Instead of offering your work to be critiqued (or dismissed... and I'm sorry to say it truly is not coherent), why not learn here, what you need to know to go back and start fresh? As you said, you're 18, a young man in the prime of life. There is no need to be impatient. Take some time to learn...
If I were you, I'd let ask Starthaus, "Ok, I'm wrong [this] is what I'm trying to describe [laws of motion, etc]... what is the correct standard formulation of this? Is there one?" etc...
It is best to ask questions first, to learn. Think, by all means, and write whatever you want, but rushing physics... it just doesn't work.
