recently i've watched a t.v documentary about how d earth formed and that the moon was 10x closer then it is 2 day and d days were shorter so i thought that the moon is slowly moving away from us and days would be longer and we might have an increase of gravity and earth would be warmer am i right or wrong

Sort of. Longer days would mean slower rotation which would have less centrifugal force than we have now, so "effective" gravity would go up very slightly, especially at the equator. The longer days would allow hotter afternoons, but the longer nights would allow colder mornings, so I don't know if the average temperature would change or not.

The moon was 14,000 miles from earth. Now it is 240,000 miles from earth. The moon continues to move slowly away from earth. The moon keeps the earth spinning around its axis. As the moon moves away, the earth's wobble will increase.
If the earths spin slows, days would become longer. If the spin quickens, the days would become shorter. The moon does not affect the rate of spin.
Nor does the moon have an effect on the earth's gravity. It gravitational pull, however, does have an effect on tides and waves. As the moon moves away, tides and waves will decrease in size.
The proximity of the moon has no effect on the earth's avarage temperature. However, if the earth's wobble becomes great enough to where the polar caps swing to the equator, melting would occur and may be blamed on global warming.

The interaction of the moon and earth due to the earth's tidal bulge causes the earth to slow down and the moon to speed up and drift away. Because the center of gravity of the earth/moon combination is now actually within the earth, and we are attracted to the combined center of gravity, the gravitational force we feel on the surface of the earth likely will change (increase/decrease depending where we are relative to the moon and combined c.g.) with great changes in time. If the earth slowed to half its rotational speed, the sun would shine directly above twice as along heating up the affected earth but the cold dark side likely would be moderated by the atmosphere. Of course the actual effects are much smaller (but are there?). You have very interesting ideas and should continue your study. good luck.

1) increase of gravity in what way? THings are now heavier on earth? No, becuase even if moon were tugging on us more, what about when earth spins so you are on opposite side? THen there would be MORE gravity.
2) As for warmth, caused by what? nearness of the moon? It doesn't generate heat.
But I think it's great that you think about these things, keep at it! Maybe you will find something great some day.

The moon's orbit is changing very slowly in relation to the earth but that does not have any effect on the gravity or temperature of the earth.

days are slowly getting longer as the earth rotation loses momentum.
gravity doesn't get stronger unless the earth increases in mass,.
although a longer day might cause changes in global temperature, although the day would have to get *much* longer to really matter - the current rate of decay in the length of the day is in a tiny fraction of a second per year.

there will be no increase in gravity and the earth getting warming has nothing to do with the moon moving away from us

Well, you are actually very right....but it is not your theory. Some guy in the 1980s already figured that one out...I read that sometime last year when I was researching about solar eclipses..
Because they say that as the moon moves further away from earth, that means that in time, a total solar ecilpse can never happen anymore...

You're actually right! I have nothing else to say. I just said that to make my question look longer so you don't need to read this but to do this you would have to read this so I will stop wasting your time now but to know this you would have to read this and....

It would have a very little bit effect.
