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.
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.
Does the escape velocity on a planet depend upon its density or mass?
No, its depends on the planets 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.
What information would you need in order to estimate the gravity on a planet?
To estimate the gravity on a planet, you would need its mass and radius. The mass can be determined through observations of the planet's gravitational effects on nearby objects or other celestial bodies. The radius can be measured through direct imaging or transit methods. With this information, you can apply the formula for gravitational acceleration, ( g = \frac{G \cdot M}{r^2} ), where ( G ) is the gravitational constant.
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 Gravitational strength of the sun?
You need to use the radius and the mass :P
What happens to the gravitational field strength as you increase the radius?
it will decrease as radius increase keeping mass same
The planet Neptune's size compared to the other planets?
Mercury's radius (at the equator) = 2440km or 0.3825 x Earths Venus' radius = 6052km or 0.9488 x Earths Earth's radius = 6378km Mars' radius = 3397km or 0.5323 x Earths Jupiter's radius = 71,492km or 11.21 x Earths Saturn's radius = 60,267km or 9.45 x Earths Uranus' radius = 25,557km or 4.01 x Earths Neptune's radius = 24,766km or 3.88 x Earths
What is the gravitational acceleration inside a planet?
The gravitational acceleration inside a planet is determined by its mass and radius. It generally decreases as you move towards the center of the planet due to the increasing mass above you.
How does the gravity of the planets vary with he mass?
The gravitational field (gravitational attraction per unit mass) at any given distance is directly proportional to the planet's mass.The gravitational field at the planet's SURFACE also depends on the planet's radius.
How can one determine how to find escape velocity in a given scenario?
To find escape velocity in a given scenario, you can use the formula: escape velocity square root of (2 gravitational constant mass of the planet / radius of the planet). This formula takes into account the gravitational pull of the planet and the mass and radius of the planet. By plugging in these values, you can calculate the escape velocity needed to leave the planet's gravitational pull.
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.
How do you find the radius of a planet?
Use the formula to find the radius of a body from its gravitational acceleration and the gravitational constant (all bodies have gravity that is proportional to their mass). See related links for a web page that will do the calculations for you.
Does the escape velocity on a planet depend upon its density or mass?
No, its depends on the planets gravitational pull

If a planet existed whose mass was twice that of earth and whose radius is 3 times that of earth.how much will a body of 1kg mass weight on this planet?
The mass is twice as much, so multiply by 2. The radius is 3 times as much--the gravitational force is inversely proportional to the square of the radius, so multiply by 1/9.2 X 1kg/9 = 0.2 kg.
