The only problem here is that a planet's gravitational field depends on how far
you are from its center. On Earth, that's easy to define, because the Earth has
a solid surface. That's where most of us spend most of our time, and so we
understand the acceleration of Earth's gravity to be the number we measure
when we're on the solid surface.
Saturn is a 'gas giant' and has no solid surface. So where should we stand in
order to compare its 'gravity' to Earth's ?
What the planetary scientists do, in order to talk about the 'size' and 'gravity'
of the gas giant planets, is: They consider dangling a barometer down into
the gas, from the wispiest thinnest gas out in space near the planet, down
and down as it get thicker and heavier. And when the barometer gets down
to the depth where the pressure of the gas is the same as the sea-level pressure
of Earth's atmosphere, they call that the 'surface', for purposes of talking about
the planet's 'size' and gravitational acceleration.
When you do that for Saturn, you find that its diameter is 9.44 times as long as Earth's diameter.
The acceleration of gravity at that depth in Saturn's 'atmosphere' has been
measured as 10.58 meters/second2 . . . about 8% greaterthan on Earth.
The force of gravity on Saturn is weaker than on Earth. Gravity is determined by both the mass of the planet and the distance from its center, and Saturn has a lower mass and larger radius compared to Earth, resulting in weaker gravitational force on its surface.
The surface gravity is 10.44 ms-2.
Yes, Saturn's gravity is stronger than Earth's gravity. The surface gravity on Saturn is about 1.07 times that of Earth.
The force of gravity at the surface of the eight planets is called surface gravity. It is the gravitational pull experienced by objects on the surface of a planet due to its mass.
The force of gravity at the surface of Uranus is approximately 8.69 m/s^2, which is about 0.886 times the gravity on Earth.
The force of gravity on Saturn is weaker than on Earth. Gravity is determined by both the mass of the planet and the distance from its center, and Saturn has a lower mass and larger radius compared to Earth, resulting in weaker gravitational force on its surface.
the force
The acceleration of gravity on Saturn is about 7% greater than it is on earth.The force of gravity there depends on the mass of the object feeling the force ...exactly as it does on earth. But whatever the object, we can predict with assurancethat when it's on the 'surface' of Saturn, the force between it and the planet will be7% greater than the force between it and the earth when it's on the earth's surface.In general terms, that force is what's commonly referred to as the object's "weight".
The surface gravity is 10.44 ms-2.
At the surface, it's about the same as the Earth's . You get a bit of variation in the value given, but, at the equator, it's about 1.065 times the Earth's. It is about 0.92 times the Earth's gravity, if you take into account the effect of the planet's rotation.
Saturn!!
Yes, Saturn's gravity is stronger than Earth's gravity. The surface gravity on Saturn is about 1.07 times that of Earth.
The acceleration of gravity at the surface of Saturn is 11.171 meters per second2. That's about 1.139 times its value at the earth's surface. Whatever the object's weight is on earth, it's about 11.4% more on Saturn.
In fact you wouldn't weigh anything, because there is no surface to place the scales. In a non surface sense, the gravitational pull or gravity is about 1.064 that of Earth. So if you weighed 100lb on Earth you would only weight about 106.4lb on Saturn.
Saturn does not really have a surface. The only hard part of Saturn is its rocky core. The "surface" of Saturn is actually hydrogen and helium kept in a spherical shape by the planet's gravity.
On Saturn's surface, things are about 8% heavier than on the Earth's surface.
Yes and No. Surface gravity is affected by density, as your distance from the object is related to the radius of the object itself (because you're measuring it on the surface). That radius, and the mass involved are related to the strenght of gravity. Absolute gravitational force however, is not related to density, as you are not necessarily standing on the object, but could be orbiting it. A real life example: Earth has an average density of~5.5g/cm^3. That's 5.5x as dense as water. Saturn, has a mass 95x greater than earths, but a density of ~0.7gm/cm^3. At any given distance from either object, Saturn's gravity is stronger. however, because Saturn is so much wider than earth, you can get closer to the center of the earth, and feel, at the surface, a higher gravity. If you stand on the surface of the earth, you experience 1g (9.8m/s^2) of gravitational force. If you stand on the surface of Saturn (if you could) you would feel 0.92g (~8.6m/s^2) of gravitational force. Saturn's surface gravity is less, despite being heavier, because it's density is so much lower. The big difference, of course, is how far from Saturn's core you are. Saturn is 60,000km across, while earth is a mere 6,000 or so. If you were to test earth's gravity not at it's surface (where the force is 1g) but at 60,000km away, you measure a force of 0.01g...far less than saturns at that same distance (0.92g). So Saturn's absolute force, is far greater.
