So imagine we have Earth and Moon, and there is a tird body(A), equidistant from moon circular tragectory in one point, from Earth. whoever, that body haven't enought graviticional Force to pull moon from his orbital around the Earth.

Whoever too, that gravitacional force provokes positive linear aceleration when moon is aproching the equidistant point(somewhat like a comet aproxing the sun, provoking increase of velocity), and provokes negative linear aceleration when the moon is moving away from that equidistant point(like when a spaceshutlle is tring to move away from Earth): as aceleration has the same direction when the moon is aproching that point, and have opposite direction when the moon is moving away from that point).

So, we can say the moons momentun is conserved, as in a complete rotation, the moon's velocity is the same.

Now, hypoteticly Imagine Human already can transform all mass in energy, by Emc^2.

So, when the moon was moving away from the equidistant point, Human would transform all the (A) mass in energy, what would happen to the gravitational Field of (A)?? would the gravitational field disappear??

2. Relevant equations

P=mv(just the concept)

E=mc^2(just the concept)

Pf=Pi(momentum conservation)

3. The attempt at a solution

So, my real point is, if gravitational field disappear, the moon, instead of losing the velocity by (A) graviticional aceleration, it won't, what makes the moon to have highter momentum than in the begining of the process...

if we would transform that energy in mass again when the moon was aproaching the point again(after semi period), the moon would get positive aceleration again...

Where is the logical error here(if there is), has there is no momentum conservation. what can't be true has there are no dissipative forces included here...

thank you in advance,
