re: energy producing experiments

[magneat]

we calculate the balance of speeds and kinetic energies in Beletsky's experiment:


https://www.youtube.com/watch?v=dq5jbPoE_Cc


Mm is the mass of the missile assembly;

Mr is the mass of the rocket body;

Mb is the mass of the ball;

Mm = Mr + Mb = M;

n <1;

Mb = n * M;

Mr = (1 - n) * M;

Vm - the speed of the missile assembly;

Vr - rocket hull speed;

Vb - ball speed;

Mm * Vm = M *Vm = Mr * Vr  + (- Mb * Vb ) =

= ((1 - n) * M) * Vr  - n * M * Vb;

((1 - n) * M) * Vr = M * Vm + n * M * Vb = M * (Vm + n *Vb);

Vr = (M * (Vm + n *Vb)) / (M * (1 - n)) = (Vm + n *Vb) / (1 - n);

Ekr - kinetic energy of the rocket body;

Ekb - kinetic energy of the ball;

Ekm - kinetic energy of the rocket assembly;

Ekoe - the addition of kinetic energy from the Obert effect;   

Ekr = (0.5 * M * (1 - n)) * (((Vm + n *Vb) / (1 - n)) ^ 2) =

= (0.5 * M * (Vm + n *Vb)^ 2) / (1 - n) =

= (0.5 * M / (1 - n)) * (Vm ^ 2 + 2 * n * Vm * Vb + n ^ 2 * Vb ^ 2) =

= (1 / (1 - n)) * 0.5 * М * Vm ^ 2 + (n / (1 - n)) * 0.5 * (n * М) * Vb ^ 2 + ((2 * n) / (1 - n)) * 0.5 * M * Vm * Vb;

Kkm = 1 / (1 - n); (fraction of kinetic energy Ekm in Ekr )

Kkb = n / (1 - n); (fraction of kinetic energy Ekb in Ekr )

Kkoe = (2 * n) / (1 - n); (fraction of the kinetic energy of Ekoe in Ekr )

Ekr = Kkm * 0.5 * M *  Vm ^ 2 + Kkb * 0.5 * (n * M) * Vb ^ 2 + Kkoe * 0.5 * M * Vm * Vb;

Ekr = Kkm * Ekm + Kkb * Ekb + Kkoe * Ekoe;
_____________________________________________________________________________

as can be seen from these elementary calculations, the theory is consistent with experience

the speed (Vk) and energy (Ekk) of the body (the body of the "rocket") depends on the speed of the body before the impact of a force pulse ...

just in case, I'll attach once again a picture where everything is painted for kindergarten

You are forgetting the source of the acceleration.
Which explicitly comes from the gravitational potential well.


Newton already told us it is easier to accelerate a moving object


We have since then learned how to derive the moment of inertia
of the moving mass relative to the applied force.


You consume less fuel accelerating while your car is moving
than you do from a dead stop.


The benefit of that rocket launching method is simply an improvement
upon our current method.
Again, not a "gain" in energy. Just less waste.


Further, if you had to raise the rocket to the elevated starting point
you're wasting more than you save by using the method.

[magneat]

about the "gravitational-potential hole" did not understand?


this simple experience shows very definitely - the greater the speed of the "body", the greater the increase in the kinetic energy of the "body" from the same impulse of force to this "body".
it's not clear why to drag here a "gravitational-potential hole" and other "difficulties"?
the experience is "simple" and "transparent", where can there be a hoax? everyone can repeat.


p.s. imho, all OU machines where something rotates take OU from mechanics ...

[sm0ky2]

How?/why? Is the rocket moving?
Before the engines fire?


Because it drops from a height
Gravity accelerates the rocket initially
Then the rockets fire and speed it up more.


You have to get the rocket up there to drop it
Or I have a genius idea.... use a 2-stage booster
The first stage can get the rocket moving
just like dropping it does in the video
The second stage can boost the already moving rocket
like when the ball fires on the video!!
Wow I should call nasa and let them know

[magneat]

you don't need to call nasa, they know about the Obert effect.
back to this experience, forget about real rockets.
the person in this video makes a "rocket start" at different points on the trajectory.
in terms of energy conservation, it does not matter at which point on the trajectory the "rocket launch" was.
energy from the gravitational field (potential + kinetic) and energy from the ball should be added up.
but for some reason, the kinetic energy of the rocket hull turns out to be maximum when the "launch of the rocket" occurs at the bottom of the trajectory, when the speed of the entire "system" is maximum. violation of the laws of physics is not here, Obert brought his effect purely theoretically, "at the tip of the pen." this is because the kinetic energy of the body is the square of the speed of the body. no mysteries, no mysticism in this.
