Usually the "pull" is given at the surface of the planet. The force reduces with distance.
The units are Newtons (unit of force) per kilogram (of the object being pulled)
The gravitational force is :
(6.67x10-11)x(mass of the planet)x(mass of the object)/(distance between the planet and the object squared)
(6.67x10-11 Newton's universal gravitational constant). Masses are measured in kilograms, and distance is measured in metres.
Finally here's the answer, in Newtons per kilogram (rounded to the nearest
whole number for the giant planets). Different sources may give slightly different numbers :
Earth 9.81
Mercury 3.71
Venus 8.90
Mars 3.70
Jupiter 26
Saturn 11
Uranus 9
Neptune 12
Gravity keeps planets in orbit as it spins it creates gravity and gravitational pull keeps the a lined
The gravitational force (F) between two masses (m1 and m2) is given by: F = (G * m1 * m2) /r^2. Where r is the distance between the masses, and G is the gravitational constant, 6.67300 * 10^-11. This means the larger the masses are, the more they pull toward each other. It also means that the closer they get, the stronger they pull.
Actually, the gravitational pull is 9.8m/s(2), therefore they all have the same grvitational pull. An object that is dropped from the same distance will land at the same time unless acted upon by and equal or greater force. As in the case on Sir Isaac Newton and the apple falling from the tree. It's the bowling ball
There are 3 possible answers to this question: Mercury, Mars, or Pluto. The simple definition of gravity is the force of attraction between two objects. Two factors determine gravitational pull: 1) the mass of the two objects and, 2) the distance between the two objects. Gravitational pull is proportional to the product of the masses of the two objects. For example, gravitational pull doubles if either of the two masses is doubled. On the other hand, gravity grows weaker if the two objects are moved farther apart. It is inversely proportional to the square of the distance between them, or if the distance is doubled between the two objects, gravity is only 1/4th as strong. So both mass and distance matter when determining gravitational pull. The big variable that the question doesn't address is how far away are you from the planet when you want to know it's "gravitational pull". Do you want to know the gravitational pull at some constant distance in space from each planet's center, or do you want to know the gravitational pull at each planet's surface. Because each planet has a different diameter, the distance from the planet's center varies from planet to planet. Since both mass and distance matter, here are the qualified answers: Pluto has, by far, the least mass of all the planets, but Pluto is now considered to be a "dwarf planet" and is no longer to be considered as a regular planet. If it were to be considered, it would have the least gravitational pull of all the planets at both it's surface and at some fixed distance in space from it's center. Mars has slightly more mass than than Mercury but also has a larger diameter. The math works out that Mars has the least gravity at it's surface. Even less than the surface gravity of Mercury because of Mars' larger diameter. Mercury has slightly less mass than Mars and a much smaller diameter. The math works out that at some constant distance in space, Mercury has the less gravitational pull than Mars because Mercury simply has less mass. Because Mercury's diameter is smaller, which puts you closer to its center, that makes its surface gravity slightly more than Mars'.
Only one force is required: gravity ... the gravitational attraction between the center of the earth and the center of the sun. If gravity were not at work, then the Earth would take off in a straight line, into deep space. And if another force were required, we'd be out of luck, since the gravitational attraction is the only force that exists.
Gravitational force is what holds all the planets in their orbits around the sun. This force is determined by the mass of the objects and the distance between them. The gravitational pull of the sun keeps the planets in their respective orbits.
Gravitational Pull?
The gravitational pull on all the planets are artificial satellites because the satellites orbit all the planets!
That explanation is logical however the sun DOES have a gravitational force because all the planets orbit around the sun.
Because Earth and all the other planets and moons have a gravitational pull. This pull is distributed so that everthing stays in orbit.
Planets orbit around the Sun because of the Sun's gravitational force, it makes the planets move by its gravitational force.
The Sun's gravity is trying to pull the planets towards it. But the planets have their own velocities and all the Sun's gravitational attraction is needed to stop the planets moving away from the Sun. The result is that the planets orbit the Sun.
No object has a pull in Newtons, or in pounds either, and I can prove it . . .My dog and I are both standing outside, on the earth.The force between the earth and me is 822 newtons (185 pounds).The force between the earth and my dog is 400 newtons (90 pounds).The force between the earth and that object he just deposited in our neighbor's yard is at least 8.9 newtons (2 pounds).Obviously, the earth pulls different objects with different forces.(And each object pulls the earth right back with the same force.)The force between the planet and the object depends on BOTH masses,AND the distance between their centers.
Planets revolve around the Sun due to gravitational force, which is strongest at the center of mass of a system. The Sun's immense gravity pulls the planets towards it, causing them to orbit around it in elliptical paths. This balance of gravitational forces keeps the planets in their orbits.
Yes, the sun's gravitational pull is what keeps Earth and the other planets in our solar system in orbit around it. This gravitational force is what maintains the planets' paths and prevents them from moving off into space.
Gravity is the force that holds planets and moons in orbit around larger celestial bodies, such as stars or planets. The gravitational pull between these objects creates a balance between the centrifugal force of their motion and the gravitational force pulling them towards each other, resulting in stable orbits.
Three of them were grabbed by the gravitational pull of the local star. There are planets that are not in our solar system.
