Gravity

No, gravity is a pulling force. It is a fundamental force of attraction that exists between all objects with mass. Gravity is responsible for holding planets in orbit around the sun and for keeping us grounded on Earth.

Not necessarily. While it is true that gravity is an inverse square relationship with distance, making closeness an important factor, mass is also important, so, for example, if two planets were in the vicinity of a spacecraft, gravity would depend on both mass and distance. Yes, distance is a squared factor, but if one planet were very much larger than the other, it could easily win out, even if it were further away.

LONG STORY SHORT: ITS BIG. ((:

Because it has a lot of mass. The more mass, the more gravity.

For a more in depth answer the reason why the sun has so much gravity is because of the density not the mass, mass is different then density, and having so much density in such a small area gives it so much gravity, and if your using this for a science worksheet the sun i composed of about 2 thousand trillion tons of hydrogen and helium.

The gravity of any body affects all other bodies.

In particular the gravity of the Moon creates the tides in bodies of water here on Earth. It also affects our planet's orbit and angle of tilt relative to the plane of its orbit.

Earths gravitational force compared to mars is greater than mars. That means that objects are easily pulled into earth, whereas it is harder to pull objects into mars, because the gravitational pull is less than earth. With that, satellites on earth could easily fly out of orbit while they are orbiting mars because they have more inertia. With that, the gravitational pull isn't strong enough to overcome the inertia.

I'm not sure if it's half or not, probably less, but the only possibility would be Mercury.

True. Mercury is the only one. Gravity on Mercury's surface is 37% of what it is on Earth.

Except for Mars, where it's 38% of its value on Earth. Mercury and Mars are the only ones.

Except for Pluto, where it's 4% of its value on Earth.

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".
