it's called pot

He got a bunch of data about how forces interact and logically deducted that in the absence of force there is no acceleration as by his law (F = m*a).

How do you know Newton knew this?

It's a logical consequence of Galilean relativity, if you think about it. (And he did.)

Also, you can easily have an experiment with very low friction which can pretty much demonstrate it.

Knew what? F = ma? He invented it.
He probably deducted it by moving a lot of shit around slippery surfaces or something.
He was also known to be kind of a hack, so maybe he just stole the discovery from someone else.

>>5308509
Probably from someone he framed for counterfeiting then had killed.

>>5308512
Or from Hooke as he used to do.
Apparently Wikipedia has the following:
>Hooke's 1666 Royal society lecture "On gravity" added two further principles – that all bodies move in straight lines till deflected by some force and that the attractive force is stronger for closer bodies. Dugald Stewart, in his Elements of the Philosophy of the Human Mind,[29] quoted Hooke's own words on his system of the world.

He knew planets kept going on at the same speed

I was being facetious because Newton was a disgusting human being. Unlike Leibniz, for example.

>what is no force acting on an object in motion
its fucking obvious
what stops somthing? a force
no force = no stop

>its fucking obvious
in retrospect QFT is obvious, as well as the decision to abort you (but seems it wasnt carried out).

>He probably deducted it by moving a lot of shit around slippery surfaces or something.


This, it is quite obvious when you do such things.

>>5308686
obvious? lol, too bad you were not born 1000 years ago, you would have discovered everything, right?

hmm...i don't know him too well and i know little physics
but the impression is that he's kind of like a math nerd(who deals mostly with number) and philosopher,
while he's working on physics(oh, Kepler's Law already existed before Newton, this answers OP's question),
these two characteristics made him wanted to make a convenient notion(as if it's a tool) with Leibniz(aka dy/dx, chain rule, product rule...what we forced kids to learn to look scientific today)

Imo, the greatness of Newton comes with luck, his contribution is still very original but isn't too hard/rare to find a replacement
because it's very easy to imagine anyone who had a mindset of mathematician+physician+philosopher at that time would have came up with similar ideas.

>>5308498
that's galileo op

He trusted his math and logic. Simple reasoning.

The guy who invented the barometer. The fact that the reading changed with time and weather led him to conclude "We live submerged at the bottom of an ocean of air." Newton almost surely drew on that, among other things.

Shut up bitch.

fuck off scum. go back to your shithole

>[Hooke's] reputation suffered after his death and this is popularly attributed to a dispute with Isaac Newton over credit for his work on gravitation, the planets and to a lesser degree light. Newton, as President of the Royal Society, did much to obscure Hooke, including, it is said, destroying (or failing to preserve) the only known portrait of the man.
>Newton delved into the occult
>Analyzed religious texts
>Told anecdote about how he discovered gravity watching apples
>Prosecuted counterfeiters in his spare time and got them hanged
Niggas did a lot of shady shit.
