what is the gravity on jupiter?
914703
the gravity on Jupiter is only 254% of the gravity on Earth. This is because Jupiter is such a large planet (and the gravitational force a planet exerts upon an object at the planet's surface is proportional to its mass and to the inverse of its radius squared). \n \nA 100-pound person would weigh 254 pounds on Jupiter.

Newton's laws of motion together with his law of gravity give a relation among\n\n    * the period P of a planet's orbit.\n    * the distance a from the planet to the Sun.\n    * a constant G measured in laboratory experiments.\n    * the mass M of the Sun. \n\n(For our purposes, assume the orbits are circles. Also assume that the mass of a planet is tiny compared to the mass of the Sun.)\n\n\nUsing this relation with P and a for the Earth gives the mass of the Sun.\n\nM ~ 2 x 1030 kg.\n\nWe will use this relation later on to get the masses of other stars.\n\nIt can also be used to get the masses of galaxies!\n\nDavison E.

Pluto, being both much smaller than Earth and less dense would have lower gravity.\n\nMars is also less dense, and is also considerably smaller, giving it a lower gravity.\n\nThe gas giants are (on average) less dense than Earth, but much much much bigger, and so have much higher gravity.  Saturn's average density is actually lower than that of water, but because there's so much of Saturn there, its gravity is quite high.  There's some sort of rule in schoolbooks about the solar system that they have to mention that Saturn could float in a bathtub, and that's what they mean.\n\nThe gravity of a planet is directly corellated to both its diameter and its density.\n\nFor example, the Earth is about 8000 miles across, and has a density of 5.5 (g/cc).  On Earth, acceleration due to gravity is 9.8 m/s2, also known as 1 G.  \n\nSaturn has a density of 0.7 (g/cc), but a diameter of 74500 miles.   Multiplying these together, and comparing to Earth's numbers, we discover that Saturn has about 1.185 times the acceleration due to gravity that Earth does.\n\nMars is 4200 miles across, and a density of 3.9 g/cc.  This comes out to a gravity 0.38 that of Earth.

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}

By Keplers 3rd Law T² α R³\n\nOr T1²R1³ = T2²R2³\nFor earth R = 1 and T = 1 and for Jupiter R = 5.2\nSo T2²/5.2³ = 1²/1³\nSo T2 = 5.2^(3/2)\n≈11.86 years

Jupiter doesn't really have a surface. It is a gas giant, and the further down into the atmosphere you go, the heavier the gaseous density. Go deep enough, and the gases behave like liquids because of the pressure.... but because it is pressurized gas, and not a true liquid, there's no rolling sea with waves at any  point in the atmosphere.\n\nDeep, deep within is thought to be a rocky core whose volume is slightly larger than the Earth. But the pressure of the gases at that depth makes contemplating the surface of that rocky core not unlike contemplating the surface of the iron core inside Earth...

now dis question i love!!! ok, u would need an anti gravity suit which would allow u to sat on top of jupiter's layer because its gas. if u put ur foot on jupiter, it would sink. so an anti gravity suit would be advised. also, ud probably need food (obviously) a flying rover so u can observe jupiter and even a weather and observations kit to be able to see the Grest red Spot. If ur goin to Jupiter's moons, u should bring stuff to help u survive, and maybe even a few scientists who can find out if Jupiter's moons' substance can help the Earth in any way. R u planning to be an astronaut or r one?? if u are, could u email me. becuz i love space and everything about it

All objects have gravity regardless of whether they are moving or not.\n\n  Moving and object faster has no effect on the strength of its gravitational field. You must be thinking along the lines of magnetism or something.\n\n  Gravity depends only on the mass of an object. a piece of paper sitting on a desk has a gravity field. But becuz the paper's mass is soo small, its gravity field is too weak to be noticed (even by a nearby ant).\n\n   To calculate the strength of an objects gravity field the equation is (M1*M2)/(d^(2))  where M1 = the mass of the object ur finding the gravity stregth for, M2= the mass of any reference object you are using to determine the relative strentgh and d^(2) is the distance between the 2 ojects squared.\n\nlooking at that equation you can see that speed and velocity and rotation does not matter.\n\ntherefore any object a person creates will have gravity, just not gravity thats as strong as a planet's. to do that you would have to make an object as massive as a planet!\n\nCelestial bodies rotate because of gravitational forces exerted on them, but the rotations have nothing to do with the strength of the gravity fields itself.

This question appears to be a math question, and not really about Neptunes gravity. You have a ratio of 5:7.\n\nThis is the ratio for earth:neptune, correct?\n\nTo calculate that, you take your weight on earth,\ndivide it by 5, and multiply that times 7.\n\nThat is your correct answer. Using an internet page to calculate the weight will NOT give you a correct answer if the problem is all about figuring out a ratio and your teacher will know you cheated.\n\nHere is a web page that can help you understand ratios:\nhttp://www.math.com/school/subject1/lessons/S1U2L1DP.html

Mass. I think.Depending on how strong the gravity is your mass changes.

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

Jupiter is the largest planet in the solar system. Its diameter is 88,846 miles (142,984 kilometers), more than 11 times that of Earth, and about one-tenth that of the sun. It would take more than 1,000 Earths to fill up the volume of the giant planet. When viewed from Earth, Jupiter appears brighter than most stars. It is usually the second brightest planet -- after Venus.\n\nJupiter is the fifth planet from the sun. Its mean (average) distance from the sun is about 483,780,000 miles (778,570,000 kilometers), more than five times Earth's distance. Ancient astronomers named Jupiter after the king of the Roman gods.\n\nAstronomers have studied Jupiter with telescopes based on Earth and aboard artificial satellites in orbit around Earth. In addition, the United States has sent six space probes (crewless exploratory craft) to Jupiter.\n\nAstronomers witnessed a spectacular event in July 1994, when 21 fragments of a comet named Shoemaker-Levy 9 crashed into Jupiter's atmosphere. The impacts caused tremendous explosions, some scattering debris over areas larger than the diameter of Earth.\n\nPhysical features of Jupiter\n\nJupiter is a giant ball of gas and liquid with little, if any, solid surface. Instead, the planet's surface is composed of dense red, brown, yellow, and white clouds. The clouds are arranged in light-colored areas called zones and darker regions called belts that circle the planet parallel to the equator.\n\nOrbit and rotation\n\nJupiter travels around the sun in a slightly elliptical (oval-shaped) orbit. The planet completes one orbit in 4,333 Earth days, or almost 12 Earth years.\n\nAs Jupiter orbits the sun, the planet rotates on its axis, an imaginary line through its center. The axis is tilted about 3¡. Scientists measure tilt relative to a line at a right angle to the orbital plane, an imaginary surface touching all points of the orbit.\n\nJupiter rotates faster than any other planet. It takes 9 hours 56 minutes to spin around once on its axis, compared with 24 hours for Earth. Scientists cannot measure the rotation of the interior of the giant planet directly, so they have calculated the speed from indirect measurements. They first calculated the speed using an average of the speeds of the visible clouds that move with interior currents, except for a more rapid zone near the equator.\n\nJupiter sends out radio waves strong enough to be picked up by radio telescopes on Earth. Scientists now measure these waves to calculate Jupiter's rotational speed. The strength of the waves varies under the influence of Jupiter's magnetic field in a pattern that repeats every 9 hours 56 minutes. Because the magnetic field originates in Jupiter's core, this variation shows how fast the plant's interior spins.\n\nJupiter's rapid rotation makes it bulge at the equator and flatten at the poles. The planet's diameter is about 7 percent larger at the equator than at the poles.\n\nMass and density\n\nJupiter is heavier than any other planet. Its mass (quantity of matter) is 318 times larger than that of Earth. Although Jupiter has a large mass, it has a relatively low density. Its density averages 1.33 grams per cubic centimeter, slightly more than the density of water. The density of Jupiter is about 1/4 that of Earth. Because of Jupiter's low density, astronomers believe that the planet consists primarily of hydrogen and helium, the lightest elements. Earth, on the other hand, is made up chiefly of metals and rock. Jupiter's mix of chemical elements resembles that of the sun, rather than that of Earth.\n\nJupiter may have a core made up of heavy elements. The core may be of about the same chemical composition as Earth, but 20 or 30 times more massive.\n\nThe force of gravity at the surface of Jupiter is up to 2.4 times stronger than on Earth. Thus, an object that weighs 100 pounds on Earth would weigh as much as 240 pounds on Jupiter.\n\nThe atmosphere of Jupiter is composed of abou

Well, that depends upon how one looks at MOVEMENT.  This is to say that though we tend to understand movement in relation to distance, to other objects, to speed, and so forth, when comparing movement in relation to the universe, the one all unifying factor of that which exists in a defined reality, actual movement becomes sort of relative, taking direction with it.\n\nBefore I pick out inherent directions of movement, let me explain a little of this subjective relativity.  What if I were to instead ask, "How much does the planet Earth weigh?"  This question similarly depends upon how one looks at the variable of weight.  See, if I ask how much a frying pan weighs or how much a barbell weighs, we can automatically presume that I am talking about its weight on Earth, how it is affected by the pull of the Earth's gravity.  So, how do we judge the pull of the Earth's gravity against the Earth itself?  Some would say you can't.  Others would maintain that the Earth itself weighs nothing, just floating in space.  Still others would determine the mass of the Earth against the pull of the sun's gravity.  Still others could match the whole solar system's weight against the pull of other systems or the pull or push from the center of the galaxy, thereafter attributing the very tiny percentage of mass for which the Earth is responsible in the equation.  Other folks would simply conceptually add up the mass of the planet and imagine what that mass would weigh if it were a great big ball sitting on our planet.  A few creative folks might pit our planet's mass against a gas giant like Jupiter, determining it's weight against that pull of gravity instead of the sun's, as if we were a theoretical super-satellite (moon) of another planet.  \n\nAll these subjective, objective, and conceptual differences come into play when we are talking about things greater than the finite.  Similar questions plague your query about movement.  So, there are not so many answers as there are different things to consider and different ways to look at it.  Here are a few options...\n\n1)  Relative to the sun, the Earth revolves.\n\n2)  Relative to its axis, the Earth rotates.\n\n3)  Relative to the plane of the solar system, the Earth wobbles on its axis.\n\n4)  Relative to a line between it’s own equator and a fixed point on the sun nearest us, the Earth tilts.\n\n5)  Relative in comparison to a planet that always has the same side facing the sun, like Mercury, or in other words, relative points on the surface of the Earth and the surface of the sun, the Earth is in an exaggerated or accelerated spin or spiral away from this presumed connector.\n\n6)  Relative to the galaxy, our solar system moves out from center in the Milky Way, the Earth moving with it.\n\n7)  Relative to other galaxies, our galaxy's mass gets caught in the collective gravitational pull of the mass of others, adjusting the direction and speed in which we travel as a galaxy and thereby affecting our solar system with Earth in it.\n\n8)  Relative to other stars in our galaxy, the Earth's proximity to the sun and small size seems more like a shake or a flicker than a revolution.\n\n9)  Relative to a center of the universe in a single big bang theory, everything, including us, moves on a vector out from center.\n\n10)  Relative to Einstein's use of LAMDA in an equation meant to unify his two theories of relativity; everything also collapses in toward center slightly in a very precise balance against the movement outward.\n\n11)  Relative to a multiple big bang theory, everything moves out from the last center of the last big bang, which in turn was already in a generalized outbound pattern from a previous big bang.\n\n12)  Relative to our branch in the implied spiral of the Milky Way Galaxy, a number of systems are moving in a sort of half-parabola ever slowing.\n\n13)  Relative to the idea of a unified greatness, like a universe, a single,
