Mate, again, i'm applying a force between two inertias that only accelerates one of them. Net system momentum is usually scalar, but here, it's now a vector, and can be accumulated over successive cycles.ME wrote:MrV. Sorry for my questions, but who would have guessed: Conspiracies 'r us !
Don't let me stop your idea of progress.
I just ask questions.

-- If you change your mind: then I may or may not had some influence...
When I look at the presented formulas, then I see it dangling full of holes - perhaps we can save the good stuff, when it's there.
Pointing out the holes should be the least of anyone's concern when it's correct or has some hidden validity.
The answer would be easy and the question simply a useful helping hand or a tool to describe that idea even better.
Perhaps the theory is in need of a small footnote here and there, that's all I try here and nothing more.
When the answers get more complicated, start to deviate from the issue and even become personal, then that's usually enough indication it's based on wrong assumptions or simply fraudulent.
The conspiracy is one's own!
-- But conspiracy-wise: don't take anyone's word for it, but everyone can check the units on mrV's changing N²-math, and they are wrong in every variant.... all without even touching the physical-validity. (That's why I usually write out those freak'n formula's: so every one is able to check)
-- It's entirely possible I don't understand a concept. In that case: who cares what I think and good luck. I can still ask questions though.
There's only one way to check for gained energy: build that damn thing !
A gain should be translatable into a continuous stream of potential energy.
Not via some formula like Ep=Ek, but the reality of raising weights in the inertial Earth frame.
Water or marbles are perfect, as long as it's external to the mechanism.
Then you'll know it is creating energy somehow.
I personally don't see that as problematic. But it's good we finally cleared that one up....mrVibrating wrote:Marcello everyone can see you're hopelessly confused.
V, I'm not against you... It seems I just have a different perspective.
Can't promise but, I'll try to stop bugging you.
Fantastic, and near-mint condition! But yeah carbs, man! Carbs, plus gravity. Never had a gravity failure from a loose connection. A fuel pump ain't the kind of thing you can just poke with a screwdriver.cloud camper wrote:Here's my donkey - actually affectionately known is Miss Piggy.

MrVibrating :Analyzing the results Alice finds out that at the end of the experiment both the green and the gray pair of masses have the same amount of momentum in an absolute sense, but different kinetic energies as the gray masses now have twice as much KE as the green masses. But that's to be expected because of the V^2 term.
Again unless I am totally out to lunch to as to what MrVibrating is trying to convey here the enigma is our definition of energy. That is because energy involves distance squared where momentum does not.Again, the energy value of momentum is not constant, squaring with velocity. Thus a constant cost of momentum, that isn't a function of velocity, is a free meal ticket, a business opportunity. A frikkin' unpatched zero-day exploit.
The significance in all of this is that we have a constant cost of momentum, vs a V^2 value.
But first you have to be able to see this input constant. That this much energy buys this much single-signed momentum, for these reasons.
Gregory wrote:Ok, here is an experiment I constructed based on the original idea.
Consider the following thought experiment:
1/ A pair of green masses (identical 1 kg) standing still in outer space, and there is a black box device (for example a constant force spring) between them. After a push of a button the black box device suddenly applies 2 * 9.81 N of force between the green masses for 1 second.
2/ There are a pair of gray masses (identical 1 kg) standing still in a gravitational field which only exist for 1 second and produces 9.81 m/s^2 of acceleration. Also here is the same black box device with 2 * 9.81 N of force applied between the gray masses for 1 second when the same button is pressed.
Now, consider Alice is watching and analysing the motion of both pair of masses on a monitor she sits before. She checks and finds that everything is ok, the experiment can be started, so she pushes on the button. Both black box device fires, and applies the same force between the two mass pairs.
The green masses in outer space accelerate equally ending up both having 9.81 kg*m/s momentum, and 48.085 J kinetic energy. Summed up in an absolute sense they have 19.61 kg*m/s momentum and 96.17 J kinetic energy.
The gray masses inside the gravitational field accelerate unequally as the force of the gravity field acting on the upper mass cancels out with the force of the black box device acting on that same mass.
The upper mass ends up with its momentum and KE unchanged while the lower mass ends up having 19.61 kg*m/s momentum, and 192.34 J kinetic energy. Summed up in an absolute sense the gray masses have 19.61 kg*m/s momentum and 192.34 J kinetic energy.
Analyzing the results Alice finds out that at the end of the experiment both the green and the gray pair of masses have the same amount of momentum in an absolute sense, but different kinetic energies as the gray masses now have twice as much KE as the green masses. But that's to be expected because of the V^2 term.
Alice concludes that although the force exerted by the black box device distributes evenly in both cases, in the case of the gray masses one half of this force cancels out against gravity leaving the motion of the upper mass unchanged, while the motion of the lower mass is accelerated twice as much, one half because of the gravity field, and the other half because of the force of the black box device.
Alice thinks this is interesting, because although mathematically the force of the black box device distributes evenly between the masses, but combined with the gravity field the case of the gray masses looks like as an uneven distribution as the motion of the upper mass remains unchanged in the process.
Hhm, is there any way to make use of the increased kinetic energy of the gray masses? - Asks Alice for herself.
Hope I didn't wrote any mistakes into the tale.

Again, my friend, i'm sorry but you've jumped onto the same initial presumption as almost everyone else here - that i'm trying to leverage some kind of instantaneous difference in absolute energies between the gravitating vs non-gravitating examples. This is not the case.daxwc wrote:Gregory:MrVibrating :Analyzing the results Alice finds out that at the end of the experiment both the green and the gray pair of masses have the same amount of momentum in an absolute sense, but different kinetic energies as the gray masses now have twice as much KE as the green masses.

Velocity is distance divided by the time so; KE=1/2mv^2 can be rewritten as KE=1/2 m *(d/t)^2
Momentum rewritten is m*d/t
So the only thing that is changed relative to one another is the distance travelled in MrVibrating Sim.
I my opinion the top mass is a red herring. One may as well say one mass starts with an impulse of x amount of force over x amount of distance and how much difference in energy is calculated due to varying amounts of impulse through the gravitational field.
What will the top mass be doing inside a wheel it is thrown up and becomes weightless to the wheel anyway.
I am sure MrVibrating will set me straight but please do so in the first paragraph. My eyes tend to water over ... yep sort of like the pot calling the kettle black.

His previous video show lots of other Newton's 3rd law demonstrations, also.

Cheers mate, fantastic what Musk is doing (wait til he gets a load of this tho). And thanks for your kind words, i'm so sorry i got into a rant at you, and just the fact that you'd raised any objection at all did give me some degree of relief for a day or two - i honestly hoped you were correct, and had found a weakness...Furcurequs wrote:MrVibrating,
I hope you are catching up on your sleep and haven't had an accident or anything due to lack of sleep.
You need to be alert on that motorcycle. I know. I spent a year using one (a 1981 Suzuki GS550E) as my primary means of transportation, and it's dangerous out there. It's probably even worse now than it was when I was doing my riding. I've had my motorcycle parked for two decades due to my health issues.
Here's a photo of someone's 1979 GS550E that looks just like my 1981 (well, when it;s all together and polished up, at least):
