Gravity

The acceleration of gravity at the surface of Mars is approximately 3.7 m/s2. Earth's acceleration is 9.8 m/s2 on average. The force that gravity would exert on an object is dependent on its mass.

Gravity is a fundamental force that governs the motion of objects in space. It is responsible for keeping celestial bodies in orbits, shaping the structure of galaxies, and influencing the behavior of light. Gravity helps to create the overall structure of the universe and plays a key role in the formation of stars, planets, and other cosmic objects.

The force of gravity of Earth is 9.8 meters per second per second (9.8 m/s*s). However if one is standing on the surface of Mars the gravity there is only 3.8 m/s*s. Gravity of a planet can be determined based on knowing the planetary mass, radius between the person and the core, and by using the constant of 6.67*00000000010* Newtons·meters/kg squared).

Most heavenly bodies (stars, other planets, etc.) are simply too far away to affect the Earth in any measurable way (with the exception of their light striking the Earth). However, there are two heavenly bodies that exert a very real effect on the Earth: the Moon and the Sun. The Moon's orbit is close enough to Earth for its gravity to affect our planet in one signifigant way. Its large mass is enough to, in effect, pull liquid water away from the Earth slightly. This is what causes the tides. The Sun is the source (indirectly) of all life on Earth. Its radiation gives warmth to the Earth, allowing it to maintain a life-sustaining temperature range. The Sun also serves as an anchor to our planet, its gravity keeping us in a steady, fairly debris-free orbit. With the exception of the occaisional comet or asteroid, the Sun and the Moon are the only two heavenly bodies that affect the Earth.

Earth gravity x 2.528. ( Wikipedia, Jupiter ).

It was really weird. I felt like I was only about 38% as heavy as when I'm on

Earth. And if I jumped up at all, I'd go crazy high, and I'd have this ridiculous

long hang-time before I came back down to the ground. It kind of felt like my

legs were really strong, and like everything was happening in slow motion.

Yes.

The moon is less massive and smaller than Earth, so the force of gravity on objects near the moon's surface is less than on Earth. The gravity of the moon is around 1/6 the gravity of the Earth. The acceleration of gravity on the moon is 1.6 meters per second per second.

Same units as are used to describe the surface gravity of the Earth, the moon,

or any other body: Units of acceleration, such as meter/sec2 or feet/sec2 .

Jun 5, 2008 - The gravity on Mars is much lower than it is here on Earth, 62% lower to be more precise. ... A person weighing 100 kg here would tip the scales at 38 kg .

the planets are situated at the orbit shell of the sun, ie they are continuously in a falling motion....however, due to the spherical shape of the sun...their falling motion never results in a collision....if the gravity of the sun was even fractionally lesser....the planets closest to the sun would change from an elliptical path to following a spiral one until they ultimately collapse in the sun....hope i helped

There is no such thing as zero gravity. The reach of gravity is infinite - you are even affected by the smallest rock in the farthest galaxy by 0.0000000000000000000000001 newtons. Weightlessness is a feeling: generally when you are in free-fall because you are in geosynchronous orbit, you are always falling just back into the loop. Astronauts in space feel the reduction in gravity and if they are not in orbit would feel differing pulls from different directions when they move to different locations.

Between the Earth and the Moon there is a point called the Lagrange point: it's the distance from both the Earth and the Moon that their pulls are equal. At this point you would 'float' forever, at least until another body comes near and adds it's gravity to the mix.

Astrology could have a possible affect on you but it doesn't take into account all objects in the Universe and thereby is a stab in the dark. The location and pulls of gravity from different objects could make you feel better or worse but we don't have the tools to measure this.

There is minimal friction on the moon because it has little to no atmosphere to create air resistance. However, there is still some friction on the moon's surface between rocks and particles when they move against each other.

The average gravitational acceleration on Mars is approximately 3.7 m/s^2, which is about 0.38 times the gravitational acceleration on Earth. This means objects on Mars weigh less compared to on Earth due to the weaker gravitational pull.

No. Earth's magnetic field is a manifestation of the electromagnetic force, which is caused by the presence of spinning nickel and iron in the core of the planet. Gravity is a separate force (one of the four fundamental forces...the other two are the weak force, involved in nuclear decay, and the strong force, involved in holding together the nucleus of an atom) which is caused by the concentration (increased density) of mass/energy in a given region of space-time. Modern physics also states that gravitational force is mediated by particles known as gravitons.

A mass of 30 kg weighs about 294 newtons (66.2 pounds) near the earth's surface.

Any force of 294 newtons (66.2 pounds) or more, pointing straight up, can lift a 30 kg load.

You weigh less on the moon compared to Earth because the moon has less mass and gravity. The gravitational pull on the moon is about 1/6th of that on Earth, so your weight appears to be lighter on the moon.

We're not sure which planet you're calling from. Here on Earth, a 100 kg person

standing on the surface weighs 981 newtons. Here in our country, as well as in

the other centers of leading-edge science and technology in Liberia and Myanmar,

we refer to that magnitude of force as "220.5 pounds".

A star's gravity increases when it gets smaller because the mass of the star remains constant while its size decreases. This results in the gravitational force becoming stronger as the distance between objects reduces, following the inverse square law of gravity.

Perturbations. These small changes can cause slight variations in a planet's orbital path due to the gravitational influences of other planets.

The concept of gravity was not invented in a specific country. It was developed over time by various scientists and philosophers, with contributions from individuals like Isaac Newton and Galileo Galilei. These pioneers observed and theorized about the force that attracts objects toward each other, leading to our current understanding of gravity.

No it can't. In order to prove it absolutely true, you would have to set up and

observe every possible reaction, and document that mass is conserved in every

one of them. Which is impossible, because there are an infinite number of possible

reactions. But it's accepted as a law because so far, no exception to it has ever been

observed.

Well, technically, before somebody else jumps on this answer and shows why it

aint true . . .

That "law" is now amended to become the Law of Conservation of Mass and

Energy, since it was shown about 100 years ago that mass and energy are

equivalent and can convert in both directions. But the total doesn't change.

No. This would be impossible. Isaac Newton showed in his Law of Gravitation that gravity depends on three things: 1. The Gravitation Constant - a tiny number (symbol G) that is universal across the univers that is a measurement of the strength of the force of gravity compared with other forces like magnetism. It is approximately 0.00000000006 2. The masses of the objects between which the force acts - the larger the mass the larger thr force 3. The distance between the objects - the smaller the distance the larger the force. So in the case of the ship, (a) the gravitation constant would be the same for the earth, ship and moon so this constant would be irrelevant in this case. (b) The earth is much more massive that the moon and so would exert a greater force on the ship than the moon ever could. So the earth would exert more gravitational pull than the earth. (c) The earth is nearer to the ship (just the depth of the sea away!) than the moon (over 240,000 miles away!) and so the earth would exert a larger gravitational pull. So the earth wins on both counts!

Jupiter has been called the "vacuum cleaner" of our solar system. Jupiter's powerful gravitational pull has likely cleared our system of many stray asteroids, comets and various space debris that might have otherwise collided with Earth. So, the gravity of Jupiter helps humans by clearing our system of dangerous object that might have impacted Earth, causing localized destruction or possibly global catastrophes if the impact would have been large enough.

A person would have to be located at a point in space called the L1 Lagrange point, which is approximately 56,000 kilometers (35,000 miles) above the surface of the Earth. At this point, the gravitational forces from the Earth and the Moon are equal, resulting in a state of equilibrium.

Gravity is what tends to make them round because gravity pulls things keep on falling and sliding towards the strongest point of gravity this process tends to cause every thing to become round. there are other forces at work such as the rotation of a body etc that also have an effect..
