What planet Force of gravity is less then half of earths?
Planets with a smaller surfae gravity than Earth are Mercury, Venus, Mars, and Uranus.
Which planet has less gravity earth or mars?
Mars has less gravity.
Why is planet earth the have the weakest gravity?
It doesn't. Mercury, Venus, Mars, and Pluto have less gravitational acceleration at their surface than Earth has. That leaves only Jupiter, Saturn, Uranus, and Neptune with stronger gravity.
Does Uranus have Weaker or stronger gravity than Earth?
The "surface gravity" is slightly less than on Earth.
Is there more gravity on Earth than on Jupiter?
The planet Uranus is more massive than the Earth and has a stronger gravitational field. So you could say that Uranus has more gravity.
If Earth's gravity is 1 what is Uranus' gravity?
You are suggesting a dimensionless scale in order to compare gravities, but you are leaving the nature of the scale a little fuzzy. However, making a comparison of Earth's and Uranus' gravities, we find that the surface gravity of Earth (.997 g's) and Uranus (.886 g's) are very close. To the nearest unit of your scale, we could conclude that the gravity of Uranus is equal to 1. Uranus is much more massive than Earth; about 14.5 times as massive. But Uranus is much less dense, with a volume of about 63 Earths. This accounts for the surface gravity being slightly less than that on earth; an earth explorer on the surface would be much farther from the planet's center of gravity than on earth. The explorer would want to do plenty of homework before descending to the surface. Uranus is a 'gas' giant, but it probably is more icy slush than gas.
What is the force of gravity in Uranus?
The gravitational field near the "surface" is about 8.69 meters/second2 (= 8.69 newton/kilogram). For comparison, Earth's gravity field near its surface is about 9.82 meters/second2. Please note that the gas planets, including Uranus, don't really have a surface like Earth does.
Is there more or less gravity on your planet than on earth?
No. My planet (and presumably yours as well) is Earth.
What is the gravitational field strength on Uranus?
Uranus being extremely massive compared to Earth surprisingly has less gravity than Earth. The low density of Uranus makes Uranus have low gravity. If someone were to stand on Uranus, they would experience 89% of the gravity on Earth.
Why does this planet have less gravity than the Earth?
because it has less mass.
How could you weigh more on earth than Uranus when Uranus is bigger?
The more gravity a planet has, the more you will weigh on that planet. The amount of gravity that you feel depends on two things: the mass of the planet and the distance you are away from the center. Uranus has about 14 times the mass of earth, but also about 4 times the radius. Because you are some much farther away from the center of the planet, the force of gravity you feel is less. The effect of mass of a planet on the gravity of that planet is equal to the effect of the radius squared. In the case of Uranus, the radius squared is about 16 times that of Earth's radius squared, and the mass is about 14 times that of Earth. An approximation of your weight on Uranus based on these numbers would be: (Weight on Earth)*(14/16) (You can calculate the gravitational pull between two objects using the formula Fg = G(m1m2)/d2 where Fg is the force of gravity, m1 and m2 are the masses of the objects, d is the distance between objects, G is 6.67x10-11, and the units are newtons, kilograms, and meters.)
Would you weigh more on a gaseous planet or a terrestrial planet?
It depends but in most cases you would weigh more on a gas planet. While the gas planets have a far greater mass than the terrestrial planets, they also have much larger radii. The strength of the surface gravity of a planet is directly proportional to its mass and inversely proportional to the square of its radius. Three of the four gas planets in the solar system have stronger surface gravity than any of the terrestrial planets. Uranus is the exception. Uranus is about 4 times the radius of Earth and 14.5 times Earth's mass, which gives Uranus a surface gravity 88.6% that of Earth. So you would weigh less on the gas planet Uranus than you would on Earth or Venus, which are terrestrial planets.
