does the earth gravity change with the fases of the moon?

Question

i am on a weight loss program that is working perfectly for me, though, i had some quetions about the earth's gravity and weight.
i know (as all of us do) that our weight is measured by mass x gravity
the gravity of the earth is said to be 9.8
my question is: does it change with the fases of the moon?
e.g. full moon = more gravity ???, thus higher weight?
new moon = less gravity ???, thus lower weight?
how much would that be?

thanks for reading and answering.

love,
leen

Answer 1

The force of gravity varies over the surface of the Earth depending on the density of the rock. You can see a gravity map which shows the differences. The force of gravity also varies depending on the position of the moon and sun (and even the other planets). So gravity will vary depending on where you are standing and the position of the sun and moon. However, these differences are very small and you would not feel the difference.

Answer 2

The gravity of the earth doesn't change with the phases of the moon, as the mass of the earth is not affected by that. However, the gravitational pull of the moon does affect things on the earth (like water, hence the tides), so things vary very slightly in weight (NOT mass!) on a roughly 25 hour cycle as the earth spins, and the moon apears to go round the earth. It's about 25 hours not 24 as the moon moves on about 1/27th of its orbit in one day, so the earth takes just under an extra hour to "catch it up". So your weight fluctuates very very slightly during the course of a day, but not so much you could easily see the difference!

I should add that this is nothing to do with the phases of the moon - it's a daily variation.

Answer 3

I want to help you, but I couldn't get over this really wierd question. The best I can say is that the sun-earth-moon system does in fact involve tidal forces, which explains why we have tides. However, the difference of one's weight as measured on a typical scale would be invisible to the eye. It would require highly specialized laboratory equipment to even be able to measure the difference.

What's more, regardless of the position or phase of the moon, even this tiny tidal effect would change throughout the 24 hour day, from maximum to minimum, just like tides do. But just for your information, the maximum variation will occur during both new and full moon, more or less.

Answer 4

i imagine the answer isn't 6 kg, because, moon has gravity and its ratio 6/a million to the earth, assume they gathering One Small Stone from the Moon, and picture that Stone has 2 kg weight on the moon, skill, that stone has its own Mass + Gravity = 2 kg (on the Moon). And now on earth, gravity will be 6 time more beneficial than the moon, skill, Stone Mass + Gravity (6 time) in case you'll calculate a million kg on the moon and six kg on earth, then its only a special between the gravity on the moon and earth, the position is the authentic mass of the stone? wish you realize.

Answer 5

The phases of the Moon are simply due to differences in the direction of sunlight shining on it due to the relative positions of the Moon and the Sun. You wouldn't expect any dramatic changes in yourself if someone simply pointed a light at one side of you, and then moved it to shine on the other side, would you? The same is true for the Moon. The PHASES of the Moon do not cause any change in gravity, nor any change in weight of objects on the Earth.

Answer 6

No. The phases of the moon aren't a result of gravity, but are a reflective view from the sun.

An argument could be made since the moon's gravitational pull causes high tides, but the effect would be minimal on people.

Answer 7

No, the gravity is a force only produced by the earth. The others planets, stars or satellites don´t have influence in it.
