Why is the sun the only gravitational force?
The sun is not the only gravitational force but it is the strongest, the earth has a gravitational force, the moon has a gravitational force etc. Any two objects have a gravitational force between them that is proportional to their masses and inversely proportional to the square of the distance between them.
How much gravity does Murcury have?
The gravitational force of a planet (or body in space) is directly related to its mass. Mercury is the planet with the least mass in the Solar System. Based on its size Mercury has only 1/3 of the gravitational force felt on Earth. Therefore, if you weigh 100-pounds on Earth, you would only be some 33 on Mercury's surface.
How could one decrease the gravitational force between a planet and an object orbiting the planet?
Gravitational force depends only on the masses involved, and on the distance. Thus, to DECREASE the gravitational force, you would have to reduce the mass of the planet or the object (take some stuff away from it); or increase the distance.
Why does the Earth have an atmosphere but other planet like bigger planet with bigger gravitational force only have so little gases?
Earth's atmosphere is the result of the gravitational entrapment of gases from volcanic release, plant and animal gas production, carbon storage in rocks and seawater, and the protective effect of Earth's magnetosphere.
Why gravitational force increases when you fly with supersonic speed?
Gravitational force depends only on an object's mass and its distance from the center of the earth. Its speed has no effect on the gravitational force.
Where earth gravitationl force become zero?
Because there is no range limit on the gravitational force, the gravitational force of the earth is only zero in the exact centre of the earth, where it cancels itself out. Realistically, the force is so small outside the immediate vicinity of earth, that it may as well be zero.
How is mars gravitational force different from earth?
Only in its magnitude ... about 38% of its magnitude on Earth.
How does the gravitational force on the surface of jupiter compares to the gravitational force on the surface of earth?
The gravitational force on the surface of Jupiter is approximately 2.5 times stronger than the gravitational force on the surface of Earth. This is because Jupiter is a much larger and more massive planet than Earth, resulting in a stronger gravitational pull.
Does gravitational force is like megnetic force due to megma rotates inside earth?
No. The gravitational force is a different force from magnetism, and depends only on the mass and the distance. Specifically, a body does not need to rotate to have gravitational force.
What is the value of gravitational field strength on a planet with half Earth's mass and half its radius?
The value of the gravitational field strength on a planet with half the mass and half the radius of Earth would be the same as Earth's gravitational field strength. This is because the gravitational field strength depends only on the mass of the planet and the distance from the center, not on the size or density of the planet.
How does the earths radius affect the gravitational force on a object at its surface?
The Earth and the object exert a gravitational force on each other, but only the Earth's is big enough to measure. So, the formula for gravitational force include the distance from one body's surface to its center and the same for the other body. The length of the radius is directly proportional to the body's gravitational force.
Only the earth exerts gravitional force on all object is it true?
Anything with mass include you and me do exert gravitational force but the earth is massive so it exert more force than any of any small object including us on earth. The gravitational force is done between two mass in following general gravitational law by Newton. F = G.M1m2/R2 We sum up G.M1/R2 as gravity = 9.81 m/s2 for M1 is earth and R = earth radius Between 2 man with m1 and m2 respectively, gravitational force between these two man is at F = G.m1m2/L2 where L = distance between center of mass (you and me for instance). Gravitational force is small compare to earth's gravitational force but it does exist.
