The gravitational force between any two object is given by Newton's basic formula for gravity:
F = G M1 M2 / R2
If the masses M1 and M2 are in kilogrammes and the distance between the objects R in metres, and the gravitational constant G is 6.670 x 10 to the power of -11, the answer is in Newtons.

What does the gravitational field strength on a planet depend on?
The gravitational field strength on a planet depends on its mass and the distance from the planet's center. The greater the planet's mass, the stronger the gravitational field, and the closer you are to the planet's center, the stronger the gravitational field.
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.
What is the gravitional field strength of the earth at its surface?
The gravitational field strength of a planet multiplied by an objects mass gives us the weight of that object, and that the gravitational field strength, g of Earth is equal to the acceleration of free fall at its surface, 9.81ms − 2.
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.
What 2 factors would affect how thick a planet's atmosphere is?
The strength of the planet's gravitational field and exposure to solar wind.
Why there will be a point between the earth and the moon at which the gravitational field strength will be zero?
At a point between the Earth and the Moon where the gravitational field strength is zero, the gravitational pull from the Earth and the Moon cancels out, resulting in a net force of zero. This point is known as the L1 Lagrange point, where the gravitational forces are balanced due to the interaction between the gravitational pull of the Earth and the Moon.
What if 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 surface t?
If a planet has twice the mass of Earth and its radius is increased by a factor of 2, the gravitational field strength at its surface can be calculated using the formula ( g = \frac{GM}{R^2} ). Here, ( G ) is the gravitational constant, ( M ) is the mass, and ( R ) is the radius. By doubling the radius while doubling the mass, the gravitational field strength becomes ( g' = \frac{2G(2M_E)}{(2R_E)^2} = \frac{G M_E}{R_E^2} ), which equals Earth's gravitational field strength. Thus, the conditions for gravitational strength to be the same as on Earth are satisfied.
What is Jupiters gravitational field strength?
Jupiters gravitational field strength is 25 Nkg^-1
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.
If you produce a scatter graph of planet mass and gravitational field strength Mercury Saturn and Jupiter appear on one line of best fit and the rest on another Why?
The gravitational field strength at a standard distance is directly proportional to a planet's mass so the need for a scatter diagram is not immediately obvious.
What is Moon's gravitational field strength?
The gravitational field strength of the Moon is about 1.6 N/kg, which is about 1/6th of the gravitational field strength on Earth.
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.
