Gravity

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..

The specific gravity of bauxite typically ranges from 2.2 to 2.5.

The Sun's gravity is strong because of its massive size and mass. Its immense gravity pulls objects towards it, keeping planets in orbit around it. The Sun's strong gravity is essential for maintaining the stability of the solar system.

The force of gravity on the surface of Jupiter is about 24.79 m/s^2, which is about 2.5 times stronger than the force of gravity on Earth. This stronger gravitational pull is due to Jupiter's larger mass and size compared to Earth.

The Relative Surface Gravity of the planets are:

thank that help a lot

1. Sun- 27.551

2. Mercury- 0.378

3. Venus 0.907

4. Mars 0.377

5. Jupiter- 2.364

6. Saturn- 1.06

7. Uranus- 0.92

8. Neptune 1.19

9. Pluto- 0.06

10. Moon- 0.17

If you wanted this because you want to know how much you weight on one of those planets then this is what you have to do... Find your weight on Earth multiply it by the relative surface gravity of the planet you would like to find out and that's your answer.

Your weight on Earth x relative surface gravity= your weight on the planet etc.

The G constant is 2/3 e-10 J m/(kg)^2. G is the energy moment per mass squared.

Energy moment is the fundamental measure of the Universe, reflected in hc, Planck's Constant times the speed of light..

The moon has less gravity, because its mass is smaller. Gravity of an object like the moon or a planet is related to its mass. The more mass, the higher the gravity.

The equation for force due to gravity is F=G(m1m2/r2 , therefore decreasing on mass (in this case the moon has less mass than the Earth) lessens the force of gravity. So the above answer was correct this just is a explanation using the equation which hopefully helps the understanding.

By the way, if 2 humans were left in a vacuum, quite close to each other, they would slowly move closer to one another. This is because humans have mass therefore they have a gravitational field.

equation for time in pendulum:

t = 2 * pi * ( sq. root (l / g))

key:

t = time elapsed ( total, back and forth )

l = length , from pivot to centre of gravity

g = acceleration due to gravity

say 1 metre length pendulum on earth @ 9.82 (m/s)/s, t = 2.005 seconds

same pendulum on neptune @ 11.23 (m/s)/s, t = 1.875 seconds

Yes, gravity exists in outer space. Gravity holds the moon in its orbit around the earth. It holds the earth in orbit around the sun. It holds the milky way galaxy together. It holds the local group of galaxies together. And the local group of galaxies might be a group of a string of galaxies held together by the great attractor.

The force of gravity on the earth is 9.8 m/s^2

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.

Gravity is the force that pulls objects towards each other. The Earth's gravity pulls everything towards its center, including us, which keeps us firmly grounded on the Earth's surface. Gravity is what gives weight to objects and keeps them from floating away into space.

Gravity is a fundamental force in our universe that influences the motion and interactions of all matter and energy. It shapes the movements of celestial bodies like planets, stars, and galaxies, holding them in place and influencing their orbits. Gravity also plays a critical role in determining the structure of space-time according to general relativity.

The acceleration of gravity on the surface of Venus is 8.858 m/s2 , so the force

is 8.858 newtons (1.991 pounds) per kilogram of mass.

That's 90.32% of the corresponding value on Earth. If you weigh 200 pounds here,

you would weigh 180.6 pounds on Venus (not counting all the stuff you'd need to

wear just to stay alive there).

Gravity causes force that pulls every two masses together.

It's the force of gravity between the sun and earth that keeps the earth

in orbit around the sun. Same goes for the other planets.

The force of gravity is also what holds you on the earth.

Gravity is everywhere, and you see the effects wherever there are two masses.

Well, honey, gravity ain't picky - it's the same everywhere! Both Mars and Mercury have gravity, but Mars is a bit heavier with about 0.38 times the gravity of Earth, while Mercury is even lighter with about 0.38 times the gravity of Earth. So, technically, they're both playing in the same gravity sandbox, just with different sized buckets.

The sun's gravity on Pluto is weaker than on Earth because Pluto is farther away from the sun. Despite both planets experiencing gravitational pull from the sun, Earth's gravity is stronger due to its closer proximity to the sun.
