70. Force is not "absorbed"

Thu Dec 7, 2023, 09:13 PM

Also, fundamentally, the gun fires against the body of the ship (not talking catching). The recoil drives it one way, but hitting the curved barrel or the curved "rail" is applying force on the ship against the recoil. You act as if the bullet hitting the ship after leaving the barrel / rail is the only thing.

Your "math" is unreadable. You can do actual formatting or images. Until then, it's unusable. . . . nt Bernardo de La Paz Dec 2023 #63

I apologize for that but if you copy and paste the things I said into AI it will fix that for you... mikelewis Dec 2023 #67

No Bernardo de La Paz Dec 2023 #69

Why this is inline with physics mikelewis Dec 2023 #3

System Design and Equation from the book mikelewis Dec 2023 #5

reminds me of project orion AllaN01Bear Dec 2023 #6

That one actually sounds more terrifying LOL! Glad that got scrubbed... this is totally different mikelewis Dec 2023 #10

Is this bullet/slug a physical item, with form and substance? oldfart73 Dec 2023 #8

Yes, you would ideally use a giant magnet... something weighing about 50 lbs... accelerated to about 2500 m/s... mikelewis Dec 2023 #11

Then it would require a mechanism to catch it and reposition it for reuse. oldfart73 Dec 2023 #13

Absolutely... this design is an engineering nightmare... mikelewis Dec 2023 #16

However... you could catch it in another railgun... mikelewis Dec 2023 #17

It takes energy to change the direction of the slugs. indigoth Dec 2023 #9

That isn't quite correct... Try this... mikelewis Dec 2023 #12

Nope indigoth Dec 2023 #18

Sorry... that's not remotely correct mikelewis Dec 2023 #19

No. It doesn't. indigoth Dec 2023 #25

You are exactly right... there is no angular momentum when it's shot... mikelewis Dec 2023 #28

Perhaps the final nail in the coffin indigoth Dec 2023 #29

Really? So let's prove this mathematically... mikelewis Dec 2023 #30

Oh please indigoth Dec 2023 #37

Wonderful... do the math then... this is all basic stuff... mikelewis Dec 2023 #38

Starting at rest indigoth Dec 2023 #39

Where's the math? mikelewis Dec 2023 #40

I did make zero equal zero indigoth Dec 2023 #41

Weak... no proof nonsense mikelewis Dec 2023 #42

Well then, indigoth Dec 2023 #43

No... I'm talking to you... mikelewis Dec 2023 #44

And to your point about NASA. mikelewis Dec 2023 #45

The short (and absolutely correct) answer is indigoth Dec 2023 #46

Well... why not really take a look at what I am saying before you continue on that stance... mikelewis Dec 2023 #47

This is correct relayerbob Dec 2023 #57

Wrong perspective. To inject angular momentum into bullet, it sucks linear momentum Bernardo de La Paz Dec 2023 #64

And as a backup... the same explanation AI style mikelewis Dec 2023 #20

One important note... AI gets the answer wrong here... and I fix it. mikelewis Dec 2023 #21

Your scheme is not fully thought out. It fails Bernardo de La Paz Dec 2023 #61

IMHO The bullets will never hit you Cheezoholic Dec 2023 #14

Well... the masses are different... mikelewis Dec 2023 #15

Physics PhD here - can't work. caraher Dec 2023 #22

Ok... you are correct... this is a poor design... let's fix that... mikelewis Dec 2023 #23

Here's My and AI's physics.... please apply real physics and fix this please... mikelewis Dec 2023 #24

And here's the final velocity... please help me make that Zero 0 mikelewis Dec 2023 #26

rec ed as something worth thinking about, but rampartc Dec 2023 #27

According to the limited physics I understand... that momentum is conserved once it begins it's rotation... mikelewis Dec 2023 #31

I ask AI to review that statement... this is the response... mikelewis Dec 2023 #32

I accentuate this effect by cutting the radius... mikelewis Dec 2023 #33

An explanation as to why this works... mikelewis Dec 2023 #34

Nice thought experiment but. EmeraldCoaster Dec 2023 #35

Saying it doesn't prove it mikelewis Dec 2023 #36

Your math is unreadable. You haven't proven anything. . . . . nt Bernardo de La Paz Dec 2023 #65

I am not proving anything. I am asking... mikelewis Dec 2023 #68

Force is not "absorbed" Bernardo de La Paz Dec 2023 #70

Why don't actual rocket scientists use this propulsion system? Ptah Dec 2023 #48

We don't know if it works or not... mikelewis Dec 2023 #50

I think I found a demonstration of your model. Ptah Dec 2023 #52

Clearly you didn't read any of this... mikelewis Dec 2023 #55

Will you provide a better illustration of your proposal? Ptah Dec 2023 #56

One hears these sort of things, and one doesn't want to believe it. NNadir Dec 2023 #49

Ok... there is no claim that this is perpetual motion... there are power supplies and limits to the length of runtime... mikelewis Dec 2023 #51

I would suggest taking a physics course. NNadir Dec 2023 #53

Well... your mathematical proofs will be fine... mikelewis Dec 2023 #54

Whatever. NNadir Dec 2023 #59
