i cant figure out earths gravity or plutos?

Th gravity of the earth is 9.8 m/s/s. The gravity of the pluto is 1/500 of the earth, or 1.29 x 1022 kg.

shosh is correct. Cause they are! The pull of gravity comes from the earth. Don't get hung up on UP and DOWN. There is no UP or DOWN... What is UP? Why would you assume that you are UP and I am DOWN? Or vise versa? There is no UP or DOWN. We have just chosen north as up as a convenience. You could hold a map in any direction or a globe at any angle it doesn't matter. We just have tried to standardize our thinking. We are working with a 1000 year old model that doesn't take into account what we know today.

weight = mass * gravity\ntherefor\nmass = weight/gravity\n\nsorry naughty but you're wrong, if you go to the moon or jupiter you will have the same mass you have in earth but you'll have a different weight

Xcuse me dude, plz be clear abt wt u wanna ask abt the PRINCILES OF GEOMETeRY

Pluto facts:\n\nDiscovered at Lowell Observatory in Flagstaff, Arizona where Northern Arizona University is located.  This observatory was initially used to look for canals on Mars.\n\nIt is debated as a planet, because it does not fit the density patterns observed from other planets in the solar system.\n\nIt has an atmosphere, which is odd given its size.\n\nIts moon, Charon, is actually located within its atmosphere, which almost makes it a double planet.\n\nIt is approximately 40 AU from the sun, which is 40 times the distance between the sun and the earth.\n\nPluto may not be the last planet in the solar system, as there is evidence of a planet, known as Xena.\n\nAfter the discovery of Neptune, some people were still concerned over a variation in gravitational forces, and the search began.\n\nPhotos of Pluto were taken in 1915 and were not discovered for almost 15 years.\n\nPluto has the highest eccentric orbit of the known planets, that is it is much more elliptical rather than circular.\n\nIs this enough?

Gravity is created by objects. "Down" is towards the center of the earth, where gravity is strongest. All planets, stars, asteroids, etc. have gravity.

Pluto is not a planet anymore... it is now a "dwarf planet."\n\nWhen it is outside Neptune's Orbit, it is 8 planets away from the Sun and when it is inside Neptune's Orbit, it is 7 planets away from the Sun.  \n\nPluto has a very eccentric orbit and spends 20 year chunks of time closer to the Sun than Neptune.\n\nAloha

Neither. It's the mass of the planet itself. Everything that has mass projects a gravitational field. The more massive an object is, the bigger its gravitational "pull". This is why objects like the Sun can support several large planets, while Pluto (which has a moon about a third the size of it) gets pulled around by its moon.

The newly discovered planet that rotates our sun is called 2003 UB313, but this question is causing a stir because since theres so many objects that are the size of pluto that rotate our sun scientists are trying to define what the term "planet" exactly means.\nfor more information look at the website below from "NASA"

a. The force of the gravitational attraction between two objects is given by the formula\n\nF= G*(M1*M2/R^2)\n\nwhere G is the gravitational constant, M1,M2 are the two masses and R is the distance between their center of masses.\n\nSince the distance between your center of mass and the Earth's center of mass is such a large distance, you can approximate this distance as being the mean, average, radius of the Earth.\n\nG can be easily found in any physics book and you are given everything else. Just plug everything in to the equation and that will give you the gravitational force between you and the Earth.\n\nb. How much you weigh is directly related to the force you just calculated. In fact, they are the same thing. Your weight is a measure of how hard the Earth is pulling you towards its center.\n\nMy old physics professor used to joke that if you want to loose weight just walk up some stairs. Since you can't loose any mass, if you are able to decrease the distance between you and the center of the Earth you will lessen the pull of gravity and thus loose weight.

gravity is a special case  of gravitation.It is the force by which earth pulls a one kg object towards it.\n\nie g=GM/R^2\n M=mass of earth\nR=Radius of earth\n\nnow force acting on a object  of mass 1 kg at a height h(from earths surface) will be \nf=GM/(R+h)^2\nwe can take out R out of bracket so that (R+h)^2 can be R^2{1+h/R}^2\nNow\nGM/R^2=g\nSo we can easily WRITE it as \nf= g/{1+h/R}^2\n\nThis f is that something we usually write as g'\n\nNow g' can be written as g{1+h/R}^(-2)\n\nFOR NOT TOO SOPHISTICATED CALCULATION\nIT CAN BE REDUCED USING BINOMIAL THEORM TO \ng'=g{1-2h/R}

You must be talking about the planet called Venus. \n\nto calculate the acceleration due to gravity, you have to use the following formula:\n\ng = GM/(r^2)\n\nwhere G is the universal constrant of gravitation = 6.673x10^-11\n\nyou know that:\n the mass (M) is 4.88 x 10^24 kg\n and the radius (r) is 6.06 x 10^6 m\n\nnow substitute into the equation. \n\ng = [(6.673x10^-11)(4.88 x 10^24)] / [(6.06 x 10^6)^2]\ng = (3.256x10^14) / (3.672x10^13)\ng = 8.867m/s/s\ng = 8.87m/s/s (thats metres per second squared)

First solve for the mass of the planet M\n\nM = 5200 kg/m^3 x 4/3 x 3.14 x (1600 x 10^3 m )^3\n  = 5200 x 4/3 x 3.14 x 4.10 x 10^18 kg\n  = 8.93 x 10^22 kg\n\nNext, use the formula for centripetal force, and set it equal to the gravitation force between the object and the planet.\n\nG (Mm)/r^2 = m v^2/r , where r is the total radius of the object, that is 1600 km  + 630 km = 2230 km.\n\nDividing out the common factors of m and 1/r, we have\n\nG M /r = v^2\n\n(6.67 x 10^-11)N m^2/kg^2 (8.93 x 10^22 kg) / (2.230 x 10^6 m)\n\n2.67 x 10^6 N m /kg = v^2\n\n1.63 x 10^3 m/s = v\n\nCheck my math to make sure, but the physics is correct.

what? further than the earth in relation to the sun, would be mars. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto and one we cant quite see yet.\nI'm not sure i understand your ?, but i hope this helps. sometime pluto comes closer than neptune, because of the orbits. click on this link, then scole down the page it brings you to.\nhttp://www.sciencemonster.com/planets.html

Since there are 63,360 inches per mile, and since the distance to Pluto from Earth is 2.67 billion miles, then just multiply it.\n\nThe real value: 1.69171E+14 inches, so that's a lot of inches lol

Consider mass m on planet Y\nas also on Earth. We have\nm*g[e]=G*m*M/R^2.........1\nm*g[y]=G*m*[2M]/[2R]^2....2\nDivide eqn.2 by eqn. 1 we have\ng[y]/g[e]\n=2M/M*[1/4R^2]/[1/R^2]\n=2/4\n=1/2
