Mass and gravity


How is gravity about the same on Mars and Mercury?

This does seem odd. Mars, with a mass that is about twice the mass of Mercury, has about the same surface gravity. Mars' mass is about .107 the mass of earth, and the mass of Mercury is about .055 the mass of earth. The surface gravity on Mars is about .38 times the surface gravity of earth, and the surface gravity of Mercury is about .38 times the surface gravity of earth as well. The difference is that the mean density of Mercury is about 5.43 grams per cubic centimeter, and the mean density of Mars is about 3.93 grams per cubic centimeter. Mercury is quite a bit more dense, so if you stand on Mercury you are much closer to the center of gravity of the planet. Mercury has a tiny slightly bit more gravity than mercury though.


Is mass larger on bidder planets or smaller?

Mass does not change with gravity. Weight increases on BIGGER planets and decreases on smaller planets.


How come earth has less gravity than other planets?

Gravity is directly related to mass. More mass, more gravity. Less mass, less gravity.


Which has a more powerful gravity a small planet or a large planet?

It would depend on the mass of the planets. The surface gravity of a planet is directly proportional to its mass and inversely proportional to the square of its radius. If two planets have the same mass but different sizes, the smaller planet will have stronger gravity because the surface is closer to the center of mass. Conversely, if two planets are of the same size, the one with more mass will have stronger gravity. Since larger planets usually have more mass than smaller ones they usually have stronger gravity, though not always.

Where do the planets get gravity?

Planets have gravity because they have mass.


Does regular planets have weak gravity?

Generally speaking, the bigger or more massive a planet it, the more gravity it has, since gravity and mass are related. the small planets such as Mars and Mercury have a weaker gravity, while the larger planets have a strong gravitational field.


Which planet has the least surface gravity?

Mercury has the smallest mass of the 8 planets at 5.5% of the mass of the Earth. It therefore has the least gravity of all the planets.


In what ways are planets different?

They do not have the exact same color, mass, diameter, number of moons, atmosphere composition, name, or gravity.


Does this planet have gravity?

All mass produces a gravity field. All planets have mass. Therefore all planets have gravity.


Why do all the planets have different fields of gravity?

Gravity is a function of mass. All the planets have different mass, so different gravity.


Does the sun give planets gravity?

No. Planets have gravity as a result of their own mass.


Does mercury have more gravity than earth?

Gravity behaves exactly the same on Mercury as it does on Earth. The forces between Mercury and any other mass are proportional to the product of Mercury's mass and the other mass, and inversely proportional to the square of the distance between Mercury's center and the other object's center. Mercury's size is about 38% as big as the Earth's size, which would place the center of an object on its surface closer to the planet's center, and cause a greater gravitational force. But its mass is only 5.5% of Earth's mass. So the force of gravity between Mercury and an object on its surface winds up being only about 37% of the gravitational force on the same object when it's on Earth's surface. That means that a person who weighs 100 pounds on Earth would weigh 37 pounds on Mercury.


What planets have large gravity?

Planets with a large amount of mass.


How does the gravity of planet mercury vary with its mass?

Gravity is directly proportional to mass.


Where does the gravity that holds the planets in their orbits come from?

The gravity that keeps the planets in orbit is the sun's gravity, which is a product of the sun's mass.


Do large planets such as Jupiter and Saturn have gravity?

Anything with mass has gravity. Anything massive enough to be considered a planet has noticeable gravity, whether it is a giant planet like Jupiter or a small planet like Mercury.
