Nope. Try removing me as an RO (so I don't get explicit write access) as I have 1 to.

Dennis the minace mod told me that it would get deleted. I don't know why it isn't done still now.

But it should...

Hi @EriktheOutgolfer any idea why ?

It automatically gets removed.

Super super weird - I can't add RO too.

I should contact a mod, not very sure to bother them or not.

@EriktheOutgolfer @SimplyBeautifulArt This is the weirdest thing : I have no main account yet I have a chat account !

Hey

Random destructions with game, and terminals or something like that

Why it's called "eleven" ?

What does that mean ?

(Also, what does the "eleven" means, in your chat description eh ?)

(Also erm are you a kid ? Your profile picture is ... erm... suspicious hehe )

@Dennis so my chat account would be deleted too, I hope ?

@Dennis Are you here now ? If you read this later, I just wanna say that for focusing on some exams, I have scheduled to delete all my SE account - will the chat account be deleted too ? (I want that)

@JohnRennie OK, I will conduct an experiment today afternoon and ping you later.

@Justwinbaby I removed because I thought orientation was wrong.

Blocks and cars and ships and helicopters and toy wagons all are same - a spherical cow.

Yeah, I could roughly undestand both - but what happens in real life - where if you pull a car hard enough with a rope, it moves, but you don't move.

:38624484 Yeah, heard it (like everyone) since childhood, and never understood it properly. That's why I'm asking here.

No, the box is a movable block, take a four wheeler car for example.

I think in (b), same thing happens, but the friction is acting equally and oposite to your movement, so you don't move, right ?

Both cases. In (a) frictionless floor, I guess you will be pulled at the block too, like two trains crashing at each other (Is this correct ?) in (b), the confusion the appearing.

@JohnRennie Nah, you are standing and pulling a block with a rope. On the other side of the rope, there's a block.

Yeah, I was trying to tell that, not the contradiction of it. (Actually, by second question, I was referring to this)

Yeah, that's what I was trying to prove with thought experiment.

Yeah, both fixed to the floor. Red box to give support to the spring.

I am in 11th grade, one year before graduating from highschool, whatever that you call in your country.

Oh yeah now I realize it's full of nonsense. What about my ohte question ?

@Kenshin Why ?

A block is there. And you are turning the handle. What's the opposing force here ?

Also, suppose in one end of the rope in this:

oh, and it this thought experiment correct ?:

@JohnRennie In both cases, (movable and constant), the block pushes at you with equal force, so why the block goes at one case, and remains constant in another ?

Let me think a bit on what you told earlier first.

Oh sorry @JohnRennie internet connection was lost for half an hour. Are you here now ?

No (But I heard it's mass x velocity). And applying analogous reasoning for case (a), this means when I push a house wall standing on an ice floor, I just get pushed back from the wall ?

Nope, but I heard of it.

Oh. So if I sit on a ice floor, and on the floor is a carom board, if strike the striker, I also get pushed back, albeit with very low velocity ?

I couldn't understand the "you also move away from the block" portion, as when I push the carom striker with my finger, my hand doesn't gets pushed back.

When I hit the block, in case (a), I could understand that the block pushes back at me at exactly the same force I pushed it (except for ridiculously high forces which breaks it and then reduces it to case (b) ), but for (b), I don't understand how the third law applies.

Imagine a cubical block lying in a frictionless place, and (a) When the block is cemented to the floor (b) When the block is just placed above the floor (i.e what happens normally).

Okay.

@JohnRennie can I ask here a (simple) mechanics question ike I did two days before ?

Anybody here so I can ask one of my confusion regarding basic Newton Ian physics ?

Okay, it is either $\sqrt{e}$ or $\frac{\pi^2}{6}$; but for very large I can see it oscillating (but you can show by trivial arguement that it never exceeds $2$ ), I think it's for C's handling of int.
