What will show scale inside rocket?

[Maciej Ma]

I want to kindly ask about opinion what will be if :

a) rocket's speed < gravitation
b) rocket's speed > gravitation

************************************************************
Earth ----- Rocket[W]m >>> constant V

[W]- scale can measure kg
[m]- person mass

Scale is showing Qearth + Qrocket

Qearth - gravitation between person and Earth (Newton's grav. force )
Qrocket - gravitation between person and rocket (Newton's grav. force)
*****************************************************

Rocket[W]m >>>>> constant acceleration

Rocket[W]m ----------------> G<V< C

G - gravitation speed in Vacuum , C- light's speed

Scale is showing Af + Qrocket
Af - acceleration forces ( rocket's engine work give constant a )
Qrocket - gravitation between person and rocket ( Newton's gravitation )

Qrocket = 0 WHY ?

Mach- first engineer who described Supersonic Speed problem

( please look on 4 animations below link (left side of page )

V= zero , V>0 , V= sound , V>sound //1,4 Mach

http://www.acs.psu.edu/drussell/Demos/doppler/doppler.htmlWhat will show scale if body m is moving faster than own gravitation ?

Rocket represent mass M
Person represent mass m

M---r----m ----------> G<V

Mass M is sending (EM) waves but waves can not touch the mass m
mass m is going faster than own signals

what will show scale ?

M---r----m ----------> G<V

M---r----m ----------> V <G More better is showingbproblem below example

P1...Sun-----------Earth ------> cnstant VP1............SUN -----------Earth >>>> constant acceleration

Sun Was in past in Point 1 . Sun started gravitation signal in P1 .

Please add to above Inverted Square Law.

How big Intensity will feel Earth ? Haw far from P1 Earth will register signal that started in P1 ?

please compare 5-6 minutes ----> constant motion situation

to 5-6 minutes >>>>>>>>>>>>>>>>>>>>>>>>>>>>>cnastant acceleration situation

Assuming that nothing on the scale changes, the only thing that will vary the reading of the scale is the acceleration (not the speed!) of the rocket relative to some nearby object in free fall. That will be true in all the cases you describe above, and is the only thing you need to know to analyze them all.

You mention the "speed of gravity" several times. There's no such thing; the gravitational field is already spread through all of space so no matter how far and fast you move, the gravitational field will already be there.

(So far there's no relativity in these problems - it's all classical mechanics)

m1-----r----mass M ----r-------m2 >>>>motion
.....Fire

Fire = that mass is changing temp.

m1 or m2 will feel more faster
that mass M is changing power of own gravitation ?

please imagine opposite direction <<<

please add to above model CONSTANT ACCELERATION !
( distance r = 1 meter or 1000 meters or 150 000 000 km )

how much time need light for distance r = 1m
how much time need light for distance r = 1000 m

how much time need gravitation to inform mass m 1 ,m2 about problem ?

To help You more
please imagine that m1,m2 are perpendicular to motion >>>

30 km/s ? ... 220 km/s
respect to what ? please read about TOLMAN test 1930 ? ( apparent position !)

I see you've got some answers already, but I find it hard to guess what you might even mean by a) and b) above.

Speed we can measure in units of velocity (meters/second for example). I'm not aware of any definition of "gravitation" that has compatible units.

And to compare quantites they must have compatible units.

I would like to provide a response to the content presented above. Firstly, the scale inside the rocket would show the combined gravitational forces between the person and the Earth, as well as between the person and the rocket. This is because the person is affected by both the Earth's gravitational force and the rocket's gravitational force.

In the case of the rocket's speed being less than the Earth's gravitational force, the scale would show a decrease in the combined gravitational force as the person and the rocket are moving towards the Earth. This is because the Earth's gravitational force is stronger than the rocket's gravitational force, and therefore the person and the rocket are being pulled towards the Earth at a faster rate.

On the other hand, if the rocket's speed is greater than the Earth's gravitational force, the scale would show an increase in the combined gravitational force. This is because the rocket's gravitational force is now stronger than the Earth's gravitational force, and the person and the rocket are moving away from the Earth at a faster rate.

In both cases, the scale would also show the effect of the constant acceleration forces from the rocket's engine. This is because the rocket is constantly accelerating and therefore the scale would show an increase in the combined forces acting on the person and the rocket.

Additionally, if the body m is moving faster than its own gravitational force, the scale would show a decrease in the combined gravitational force. This is because the gravitational force of the body m is not strong enough to keep the body m and the rocket together, and the body m is moving away from the rocket at a faster rate.

Furthermore, the concept of the Inverted Square Law would also apply in this situation. This law states that the intensity of a signal, in this case, the gravitational force, decreases with the square of the distance from the source. Therefore, the further away the body m is from the rocket, the weaker the gravitational force would be, and this would be reflected on the scale inside the rocket.

In conclusion, the scale inside the rocket would show the combined gravitational forces between the person and the Earth, as well as between the person and the rocket. It would also show the effect of the constant acceleration forces from the rocket's engine. Additionally, in the case of the body m moving faster than its own gravitational force, the scale would show a decrease in the combined gravitational force, and the Inverted Square Law would also apply.
