What planet has the force of gravity that has half of the pull exerted by gravity on earth?
answer is mars but all planets have a gravitation effect on the earth even gas planets
What is acceleration due to gravity on surface of planet that has radius half that of earth and same average density as earth?
The acceleration due to gravity on the surface of the planet would be four times greater than that of Earth. This is because the acceleration due to gravity is directly proportional to the radius of the planet, and inversely proportional to the square of the radius. Since the radius of the planet is half that of Earth, the acceleration due to gravity would increase accordingly.
How large is Mars planet?
half of earths size
What planet has a gravity pull of less than half of earth?
the sun
Would the gravity on the planet Mercury squash someone?
No. The gravity on Mercury is less than half that of Earth.
What force of gravity here was less than half the pull exerted by gravity on earth?
pokemon
What planet has the force of gravity here that has less than half of the pull exerted by gravity on earth?
I'm not sure if it's half or not, probably less, but the only possibility would be Mercury. True. Mercury is the only one. Gravity on Mercury's surface is 37% of what it is on Earth. Except for Mars, where it's 38% of its value on Earth. Mercury and Mars are the only ones. Except for Pluto, where it's 4% of its value on Earth.
If a planet has 4 times the density but half the diameter of earth is it's gravity stronger or less?
No, the gravity of this planet will not be greater than that of earth. If the new planet has a mass equal to that of earth, its total gravity will be the same. There is a little ambiguity regarding 4 times earth density and half the earth's diameter if the idea is to keep the mass of this proposed planet the same as the earth. But setting that aside and assuming that the mass of the new planet is the same as earth's, the gravimetric field will be the same. Gravity is proportional to mass, and identical mass yields identical gravity. Now to the good part! The surface gravity of the new planet will be considerably higher than the surface gravity of earth. Both planets have the same mass and the same gravity, but a person standing on the surface of the new planet will be experiencing a whole lot more force pulling on him. All the mass of the new planet is beneath this person, but he's a lot closer to the center of gravityand will weigh a whole lot more.
Why are the planet round?
The force of gravity, pulled this molten material inwards towards the planet's center into the shape of a sphere. Later, when the planets cooled, they stayed spherical. Planets are not perfectly spherical because they also spin.
The force between a planet and a spacecraft is 1 million newtons.What will the force be if the spacecraft moves to half its original distance from the planet?
The force is inversely proportional to the square of the distance. So, half the distance means four times the force. So, the answer is: 4 million newtons. additional note: This is true only if the distance referred to is the distance to the center of the planet or if the distance to the planet is great enough to make the radius of the planet insignificant.
How the weight and the mass will change if a planet has gravity half as strong as Earth?
Mass remains the same; weight will be one half that of the same mass on earth.
What does the planet Saturn look like'?
It has no solid surface. It would hold 9 and a half earths on its face! Looks a bit like a squished ball.
