For a planet to have the same gravitational field strength at its surface as Earth while having twice its mass, its radius must increase. The gravitational field strength ( g ) is given by the formula ( g = \frac{G \cdot M}{R^2} ), where ( G ) is the gravitational constant, ( M ) is mass, and ( R ) is radius. If the mass ( M ) is doubled, to maintain the same gravitational field strength ( g ), the radius ( R ) must be increased by a factor of ( \sqrt{2} ), not 2. Therefore, the radius would need to be larger by a factor of approximately 1.414.

What If a planet has twice the mass of Earth its radius would have to be larger by a factor of 2 for the gravitational field strength at the planet and surface to be the same as on Earth and s?
If a planet has twice the mass of Earth, its radius would need to be larger than Earth's to maintain the same gravitational field strength at its surface. Specifically, to achieve equivalent gravitational acceleration, the radius must increase by a factor of about 1.414 (the square root of 2), not 2. This is because gravitational field strength is directly proportional to mass and inversely proportional to the square of the radius (g = G * M / r²). Therefore, a radius larger by a factor of 2 would actually result in a lower gravitational field strength than that of Earth.
Is there any relationship between the mass of a planet and its gravitational field strength?
Yes, there is a relationship between the mass of a planet and its gravitational field strength. The greater the mass of a planet, the stronger its gravitational field strength will be. Gravity is directly proportional to mass, so planets with more mass will have a stronger gravitational pull.
Why is the gravitational field strength of earth and moon are different?
The gravitational field strength of Earth and the Moon differs because each celestial body has its own mass and radius. Earth is more massive and has a larger radius compared to the Moon, leading to a stronger gravitational field on Earth. The gravitational field strength decreases with distance from the center of the body, so being closer to Earth results in a stronger gravitational pull compared to being closer to the Moon.
If a planet is larger is it weaker or stronger?
A planet's size does not directly determine its strength; rather, strength can refer to various factors like gravitational pull, structural integrity, or magnetic field. Generally, larger planets tend to have stronger gravitational forces due to their greater mass. However, factors such as composition and core structure also play significant roles in determining a planet's overall strength. Thus, a larger planet can be stronger in some respects but not necessarily in others.
Do all planets have the same gravitational field strength as earth?
No, the gravitational field strength on each planet depends on its mass and radius. For example, Jupiter has a stronger gravitational field than Earth due to its larger mass, while Mars has a weaker gravitational field because it is smaller and less massive than Earth.

What affect does mass have on the strength of a gravitational force?
The strength of the gravitational force between two objects is directly proportional to the product of their masses. This means that the greater the mass of the objects, the greater the gravitational force between them.
Why does earth excert o stronger gravitational force than the moon?
It exerts a stronger force on us (when we are on it's surface) for two reasons: 1. It has a larger mass (gravitational field strength increases with mass). 2. It is closer (gravitational force is inversely proportional to the square of the distance from the object's centre of gravity).
Is there any relationship between the mass of a planet and its gravitational field strength?
Yes, there is a relationship between the mass of a planet and its gravitational field strength. The greater the mass of a planet, the stronger its gravitational field strength will be. Gravity is directly proportional to mass, so planets with more mass will have a stronger gravitational pull.
Is gravitational force is stronger or weaker?
Gravitational force of the moon is 1/6th the gravitational force of the Earth. The larger the object, the greater gravitational force it will have.
Why is the gravitational field strength of earth and moon are different?
The gravitational field strength of Earth and the Moon differs because each celestial body has its own mass and radius. Earth is more massive and has a larger radius compared to the Moon, leading to a stronger gravitational field on Earth.

What affect does mass have on strength of a gravitational force?
The larger the mass, the stronger the gravitational force.
What is the definition of gravitational strength and how does it impact the motion of objects in space?
Gravitational strength refers to the force of attraction between two objects due to their mass. In space, this force influences the motion of objects by causing them to orbit around larger objects, such as planets or stars. The strength of gravity determines the speed and trajectory of these objects as they move through space.
Why gravity is different on different bodies in our solar system?
Gravity varies on different bodies in our solar system primarily due to differences in mass and size. The strength of gravitational attraction is directly proportional to an object's mass; more massive bodies exert a stronger gravitational pull. Additionally, the radius of the body affects gravity; for instance, a larger radius can decrease the gravitational acceleration experienced at the surface. Consequently, smaller celestial bodies like the Moon have weaker gravity compared to larger ones like Earth or Jupiter.
Where is the strengh of gravitational forcen in the poles or equator?
If the Earth were a (homogeneous) sphere, the gravitational force on its surface would be the same everywhere. I think that the gravitational force is slightly larger at the equator (center bulging Earth). But you might not measure it because of the rotation of the Earth.
