is gravity stronger on the earth or on the moon and why?

Your weight is less on the moon.  This is because the force of attraction between you and the moon depends on your mass, the mass of the moon and how far you are apart.  While, on the moons surface, you are quite close to some bits of the moon, you are a long way from the bits on the other side and the average effect is as though all the moons mass was somewhere near the middle. There is a _lot_ more mass in the earth than the moon but when you are standing on the surface of the earth the center is further away and the attraction varies as 1/distance^2 so, despite the earth's mass being more than 80 times the moon's you weigh only about 6 times as much.

To understand this quandary you must look at a much bigger picture. since gravitational force is determined by an objects mass the earth actually exerts a much greater force on the object than the object exerts on the earth. Now this is where you must remember Newton's second law - if an unbalanced force acts on an object the object will accelerate in the direction of the force. The unbalanced force is the force of gravity the larger mass (earth in this case) exerts on the smaller object. The acceleration in the direction of the force is what we call gravity. It is true that the object exerts a reaction force but the maximum force it exerts is only the force of gravity it can generate based on it's mass. Since it weighs less it's force is not strong enough to move the earth.

The moon's gravity as felt on earth is indeed much weaker than that of earth, but it acts on the entire area of the earth, in particular on the earth's water layer, a shell 8000 miles in diameter. This weak but widespread gravity force raises slight bulges only a few feet in height, a small distortion of such a huge shell. The two bulges are located close to the areas nearest to and farthest from the moon, the points of greatest and smallest moon gravitational pull. Rotation of the earth causes these bulges to travel around the earth's water layer. Tide can be thought of as an extremely long wave that occurs at predictable times (about twice a day) with predictable amplitudes. Resonant sloshing in the ocean basins amplifies the water height disturbances on shore.\nThe greater tidal amplitude at full and new moons is due to the additive effect of solar gravity when the sun, earth and moon are all more or less in line. Incidentally, the size of ordinary waves is only marginally related to tides.

75 newtons (around 17 pounds)....the moon's gravitational pull is only about 1/6 that of earth.

The force of gravitational attraction that the earth exerts on the moon tending to pull the moon towards its center, is exactly balanced by the centrifugal force (that tends to take the moon away from the earth) on the moon due to its (approximately) uniform circular motion.\n\nMathematically,\n\nFg   =     Fc

The attractive force of the "magnet earth" is much smaller than it's gravitational force. In fact it's negligibly small. Proof: put an iron object on the table, like a knife. Despite it being much more closer to the earth than the moon, it will not budge.

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)

Mass is a constant.  \n\nWeight depends on gravity.\n\nSo, your mass is the same on earth and on the moon,\nbut you would weigh one-sixth as much on the moon\nas you do here on earth.

gravitational pull is different in different places on earth. but it is fixed. we cannot change it locally or globally. bcoz it depends on earth's mass, which we cant change.

the net force acting on the moon is directed towards earth.\n\nthe net force acting on earth is directed towards the moon.\n\nthe force on the earth is weak and the earth is very massive so it only causes the earth to wobble, however the force on the moon is large and it is less massive so it orbits the earth.

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?

tides are a result of the gravitational pull from the moon

2, exactly. They have been hit by astronaut Alan Shepard on Apollo 14, and they have NOT floated away - the gravity on the moon is six times less than Earth's, not inexistant. Look for the quote from Shepard in the link:

No. On the moon, you would "weigh" about 1/6 what you do on earth.  Although that's a much lower number, it's still not close enough to zero that you could escape the moon's gravitational pull simply by jumping.

The moon's orbit is in a balance between centrifugal force (outward motion) and gravitation (inward force toward the earth).

neap tide is the answer.\n\nExplaination. Since it is the effect of the moon and sun's gavity that causes tides, there are high tides closest and farthest away from the two of them. When they are lined up, spring tide occurs, resulting in the highest and lowest possible tides. However, when the sun, moon, and earth are at a 90 degree angle, the difference between high tide and low tide is the least(Because the effects of gravity are spread out). This is neap tide.\n\nPS. At neap tide there is still a visible distinction between the high and low tides. This is because the sun and moon's gravity and distance from Earth are not the same.

saad, hi!\n\ni found this neat description for you... it's put in simple layman terms...\n\nQ. What's the difference between weight and mass?\n\nA. As long as you stay on Earth, the difference is more philosophical than practical.\n\nQ. Uh...what do you mean by that?\n\nA. Well, mass is a measurement of how much matter is in an object; weight is a measurement of how hard gravity is pulling on that object. Your mass is the same wherever you are--on Earth, on the moon, floating in space--because the amount of stuff you're made of doesn't change. But your weight depends on how much gravity is acting on you at the moment; you'd weigh less on the moon than on Earth, and in interstellar space you'd weigh almost nothing at all.\n\nQ. But if you stay on Earth, gravity is always the same, so it really doesn't matter whether you talk about weight or mass.\n\nA. That's right...but scientists still like to be careful about distinguishing between the two. If you talk about the mass of an atom--as I will do from now on--you're always talking about the same thing; if you talk about its weight, what you mean depends on where the atom is. \n____________________________________________\n\nhope this helped...!\n\nenjoy!
