If one were to stand on it, they would simply sink until they eventually arrived at its (theorized) solid core. As a result, Jupiter's surface gravity (which is defined as the force of gravity at its cloud tops), is 24.79 m/s, or 2.528 g.
According to Newton's Law of Universal Gravitation, Jupiter pulls you up 34 million times less than Earth pulls you down. Jupiter's "pull" is utterly feeble. So it's all in your mind.
Jupiter's environment is probably not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.
Now, coming to the question, Jupiter has the highest surface gravity of all the planets.
For a one-solar-mass black hole, this is about 1.6 trillion g's (i.e. 1.6 trillion times the gravitational acceleration we experience at the surface of the Earth).
Changes in speed are expressed in multiples of gravitational acceleration, or 'G'. Most of us can withstand up to 4-6G. Fighter pilots can manage up to about 9G for a second or two. But sustained G-forces of even 6G would be fatal.
An untrained individual not used to the G-straining manoeuvre can black out between 4 and 6 g, particularly if this is pulled suddenly. A trained, fit individual wearing a g suit and practicing the straining manoeuvre can, with some difficulty, sustain up to 12-14g without loss of consciousness.
Gravity on Neptune:
All told, it is 3.86 times the size of Earth and 17 times as massive. But, being a gas giant, it has a low density of 1.638 g/cm3. All of this works out to a surface gravity of 11.15 m/s2 (or 1.14 g), which again is measured at Neptune's cloud tops.
There is no such thing as zero gravity in space. Gravity is everywhere in the universe and manifests itself in black holes, celestial orbits, ocean tides, and even our own weight.
On the moon you can jump 9 feet (2.7 meters) in the air from a standing position compared to just 1.5 feet (0.5 m) on Earth. Near Jupiter, the most massive planet, you'd only achieve 6 inches, while on Martian moon Phobos, a jump would launch you straight out into space.
The surface gravity on Uranus is about 86% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh 86 pounds on Uranus (assuming you could find someplace to, well, stand).
Kirby often says, “At 10 G's, it's hard to breathe and feels like a house is sitting on your chest.” That's a ton of pressure, literally! When a person begins to lose consciousness due to positive G's, this is called G-lock.
While commercial flights exert only very minimal positive and negative G-forces on passengers, several orders of magnitude greater are the G-forces experienced by astronauts, fighter pilots and stunt pilots. These types of pilots can experience brief periods of extreme forces of nine and 10 Gs.
With upgraded power and capacity, 10G will enable creators and innovators to fulfill their dreams while providing reliability and security. How fast is 10G force? G/10 = 3.2 ft/sec/sec = 2.2 MPH per second (3.2*3600/5280=2.2 approximately!) In other words, the speed increases by 2.2 MPH every second.
A black hole with a Schwarzschild radius of about a centimeter, which would make it about the size of a coin, would have about the same mass as the Earth. The reason the Earth will be destroyed but not simply swallowed up is because the Earth will be resisting the black hole in at least two ways.
Some black holes, called supermassive black holes, may have as much matter as 1000 million Suns! The more matter something has, and the closer an object is to that matter, the stronger the gravity.
Even if we see the universe from a point very close to the apparent event horizon, the time dilates to such an extent that the time of the locations away from tne universe will be much faster (say 1 second for the observer near blak hole will be 100000 years for an observer on earth).
As suggested by its name, the strong force is the strongest of the fundamental forces. It is about 100 times stronger than electromagnetism and 100 trillion trillion trillion times stronger than gravity. However, the strong force only has influence over very, very small distances.
The sun is about 1,000 times more massive than Jupiter, and these two bodies affect one another proportionally according to distance and mass, so the amount Jupiter's gravity pulls on the sun is one-thousandth the amount the sun's gravity pulls on Jupiter.
A world very different from Earth...
However, Saturn's gravity is only 1.08 times the gravity on Earth because Saturn is such a large planet. An object weighing 100 lbs on Earth would weigh 108 lbs on Saturn. Saturn is less dense than water. If there were a body of water large enough to hold Saturn, it would float!
