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.
When you are on a planet your weight depends on how massive the planet is and how close to the center you are (planet's radius). That's because the planet is attracting you with the force of gravity and the force is larger if its mass is larger and the distance to the center is smaller. Since the different planets have different masses and different sizes the gravitational force on you will be different, so your weight will be different.
Sara would weigh exactly the same as on Earth. The radius of the planet does not make any difference on ones weight. The mass of the planet is the crucial factor.
Weight is technically the force that gravity exerts on you. Mass is how much matter you "are". Mass times the acceleration of gravity will equal your weight. Newton discovered that the force of gravity [your weight] is equal to a constant times the mass of the planet times the mass of you all divided by the radius to the center squared. This equation shows that the weight is inversely proportional to the radius to the center squared. Thus, as the radius to the center increases, the weight will decrease. So if you move away, your weight will decrease.
Weight is caused by being pulled down by a planet, therefore it changes from planet to planet. When in space we orbit a planet and the acceleration of the orbit counter-acts the weight - resulting in weightlessness.
Mercury is the lightest planet, with a mass of 0.055 that of Earth.
No. Weight is the measure of how much force a planet pulls an object, that force is determined by the planet's mass and radius, and each planet has a different mass and radius.
The weight of an object on the surface of a planet depends on ...-- The mass of the object.-- The mass of the planet.-- The distance between the center of the object and the centerof the planet, i.e. the planet's radius.

That is answerd by Newton's law of gravity:F = G M1M2/ R2F is the force, your weight, M1 is your mass, M2 is the planet's mass, and R is the radius of the planet. G is the universal gravitational constant.

There is no maximum weight that a planet can get to. A planet's weight depends on its mass and the gravity it has.
That would depend on the planet's radius. The strength of gravity depends on both the mass of the object in question and the distance from its center of mass. If the planet in question had the same radius as Earth, then the person would weigh 200 lbs as gravity would be twice as strong. If the planet had the same density as Earth it would have 1.26 times Earth's radius and gravity would be 1.26 times as strong and the person would weigh 126 lbs. If the planet had about 1.41 times Earth's radius then that person's would weight 100 lbs.

Weight is a force acting on a smaller mass due to a gravitational interaction with a larger mass. The weight of an 80 kg human on a 5.974*10^24 kg planet with a radius of 6378 km (this is earth) is equal to 784 Newtons (or 176 lbs).
The more gravity a planet has, the more you will weigh on that planet. The amount of gravity that you feel depends on two things: the mass of the planet and the distance you are away from the center. Uranus has about 14 times the mass of earth, but also about 4 times the radius. Because you are some much farther away from the center of the planet, the force of gravity you feel is less. The effect of mass of a planet on the gravity of that planet is equal to the effect of the radius squared. In the case of Uranus, the radius squared is about 16 times that of Earth's radius squared, and the mass is about 14 times that of Earth. An approximation of your weight on Uranus based on these numbers would be: (Weight on Earth)*(14/16) (You can calculate the gravitational pull between two objects using the formula Fg = G(m1m2)/d2 where Fg is the force of gravity, m1 and m2 are the masses of the objects, d is the distance between objects, G is 6.67x10-11, and the units are newtons, kilograms, and meters.)
Weight affects a balls bounce Size affects the weight and the radius affects the size The most important factor is what material the ball is made from.
