What determines how much gravity on a planet has?
Its mass. More mass=more gravity Also the distance from the planet's center to its surface, i.e. its radius.
What is mass of 2.0kg of Au on planet 3x gravity on earth?
Mass is a measure of how much matter is in an object; it does not depend on gravity. The mass of 2.0 kg of gold is 2.0 kg no matter where the gold is, so on a planet with three time the gravity, the mass would still be 2.0 kg.
How much gravity do the other planets have?
The amount of gravity is not really quantifiable, but the gravitational force of a planet on a standard mass at a standard distance is proportional to the planet's mass.
Does planet Mars have gravity?
Yes it does but not as much as earth does. Every object that has mass also has gravity.
Is it true that the bigger the planet the stronger the gravity?
For the most part, yes. But the actual determining factor for how much gravity a planet has is based on its mass, and since size and mass are often related it is somewhat accurate to say that the bigger the planet is, the more gravity it will have.
Why is there more gravity on Pluto than on Earth?
There isn't. The "surface gravity" is dependent on the mass (of the planet, etc.) and the distance of the surface from the center of mass. Pluto has MUCH LESS mass than Earth and the gravity is much less on Pluto.
Determining How much gravity a planet has?
There's a very definite relationship ... which we can write as a fairly simple mathematicalformula ... between the planet's mass, its radius, and the acceleration of gravity at its surface.
What determines your weight on a planet?
Your weight on a planet is determined by the strength of its gravity. Gravity is the force that pulls objects towards the planet's center. The more massive the planet, the stronger the gravity, resulting in a greater weight for objects on its surface.
Why is the surface gravity of Pluto the weaker than that of the planets in our solar system?
Pluto has a weaker surface gravity than a planet because it has much less mass than a planet has.
What holds the Earth's atmosphere in place?
The atmosphere is held in place by the earth's gravity. Gravity is related to mass, the more mass a planet has, the more gravity. A much smaller planet like mercury or a body such as the moon will have less gravity, not enough to hold an atmosphere - the gravity is not strong enough to prevent the gas particles from escaping into space.
How much would a 100 lb person weigh on a planet twice the mass of earth?
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.
What came first the planet or it's gravity?
The particles of rock and dust that the Earth much later would be made from had gravity. Much, much, much later, the planet was formed. Every object that has mass also has gravititational attraction, even your body. Even a sewing needle has gravity.
