If the mass of the moon is low - about eighty times less than the earth, why is the gravity so high?

The Moon's mass is less but you're closer to the centre.   Gravity goes up as the square of your distance from the centre.

No, because gravity is inflicted by the mass of an object... and we have a very massive object near by that will outweigh any gravity caused by a humble golf ball or a slightly proud bowling ball: it's called the Earth.\n\nBasically, gravity is a force of attraction, so a large object will attract a small object. That is what keeps the moon orbiting the Earth, and the planets orbiting the Sun. Even here on Earth objects are attracted to each other, but the Earth's gravity makes that force almost impossible to measure or detect.

If the earth wasnt tilted on its axis, we probably wouldnt have any gravity.  The tilt helps with the gravitational pull of everything and the moon itself.

The earth exerts a powerful gravitational attraction for the moon (the moon also exerts a similar but lesser attraction for the earth that raises tides both in the ocean and to a lesser extent in the earth's crust that move about the earth as it spins).  The earth's attraction has raised a bulge in the moon facing earth that is therefore slightly closer to the earth and more strongly attracted.  If a huge meteor struck the moon (as in the past) trying to rotate it, it would have to overcome the earth's attraction for the bulge; thus the moon always faces its bulge toward the earth.  If the moon did spin at one time, the bulge would have helped arrest the motion relative to earth as it deleloped and froze solid.

Assuming life on earth still existed and that water\ncould still be found (not all frozen), the tides \nwould be smaller, because the Moon influences the\ntides about 90% but the other 10% influence comes\nfrom the Sun's gravitational force... That's why\nthe tides are higher at New Moon and Full Moon, \nbecause both the Moon and Sun are pulling along\nthe same line, whereas at first quarter and last\nquarter Moon, the tides are relatively lower, \nsince the Sun and Moon's gravitation somewhat\ncancells each other out

The gravitational pull on the moon is 1/6 that on Earth.  Note that on the Moon only your Weight (Pulling force of planet,etc) changes and not your Mass (Measure of amount of matter in an object).  So if your Mass is 100lb (approx 45kg) on Earth, it would still be 100lb on the Moon.  \nHowever your Weight changes from being 450N (450 newtons using the equation Weight = Mass x gravitational field strength on earth which is taken as 10N/kg) on Earth to 75.2N on the moon (1/6 that on Earth where g = 1.67N/kg)

It turns one revolution for every orbit it makes.  This happens because of tidal locking.  Basically that means the part of the moon closest to the earth gets pulled slightly more then the further side.  This means a slight bulge forms on the moon facing earth.  This side has more mass then other part of the moon thus is "heavier."  The earth's gravity then pulls on the buldge more then the rest of the moon making the moon slowly slow down or speed up in its rotation until the bulge always points towards the earth, thus one side always faces us.

if the weight of the person is measured on Earth to be equal to 85 N then the mass is to be equal to \n\nm = F/a = 85/9.8 = 8.67 Kg\n\nif the weighting is taken on the moon then the mass is equal to \n\nm = 85 / 1.67 = 50.9 Kg

If an object has mass, then it exerts gravity. The larger the mass the more gravity it exerts. Earth exerts gravity, but so does the moon, and the sun. The sun exerts a lot more gravity because it has more. Weight is a function of mass and gravity. So if you're asking about weight of earth, then in relation to what?

Be careful not to confuse the concept of weight with the concept of mass. The Earth's weight would depend on the acceleration due to gravity (Here on Earth we call it 'little g' and it's 9.8 m/s squared) on the enormous planet with a huge bathroom scale that you could set the whole planet Earth on. The Earth's mass doesn't change (except for increasing steadily due to cosmic dust accumulation) when you move it from gravitational field to gravitational field.  Likewise your weight changes when you walk on the moon, but your mass stays the same. It's the different acceleration due to gravity  (The moon's instead of the Earth's) that changes your weight.

the moon does have gravity, and the flag was not waving it was shaking when they put it in the ground, \n\ncheck this out this video\n\nhttp://www.youtube.com/watch?v=qMrUpCjVHIk

Things would weigh less than on earth\n\nst

33.3 lbs\n\nThe moon's gravity is 1/6 that of earth.

Gravity is everwhere but less or more, depends on the matter.

Gravity...or if you mean why doesn't it come over the land...then that is because the land is higher then the sea, hence there is not enough water in the sea to raise it above the land.

The Earth as a whole can be considered a single mass, m1 and another object, for example you, or the moon, or an apple, is considered another mass, m2. The gravity force between them is given as:\n\nF = G*[(m1*m2)/r^2]\n\nWhere G is the Gravitational constant and is equal to:\n6.67x10^-11 N m^2/kg^2\n\nSo the root cause of the Earth's gravity is it's mass and how it pulls on other masses as given by the equation above. \n\nYou can see that with two very massive objects like the Earth and the Sun you get a much bigger force than with smaller masses like 2 people. THat's why the Earth is kept in orbit about the Sun but you don't feel a force pulling you towards other people for example.

it has gravity indeed, but less than earth\n\n:> peace\n.
