There's a very definite relationship ... which we can write as a fairly simple mathematical
formula ... between the planet's mass, its radius, and the acceleration of gravity at its surface.
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.
Yes, there is a relationship between a planet's distance from the sun and its surface gravity. The closer a planet is to the sun, the stronger the gravitational pull from the sun, which can affect the planet's own gravity. However, other factors, such as a planet's mass and composition, also play a significant role in determining its surface gravity.
Its mass. More mass=more gravity Also the distance from the planet's center to its surface, i.e. its radius.
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.
No. It is the other way around; gravity depends on mass.
Yes it does but not as much as earth does. Every object that has mass also has gravity.
Planet Mercury and Planet Earth are both rocky planets. But Mercury is much smaller than Earth, so has much less force of gravity. Your answer is "No".
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.
Yes, gravity does depend on the planet you are on. The force of gravity is determined by the mass of the planet and your distance from its center. Therefore, gravity will be different on each planet based on these factors.
Pluto has a weaker surface gravity than a planet because it has much less mass than a planet has.
Io is a moon of Jupiter, not a planet. Surface gravity is about 18% of the gravity on Earth.
Surface gravity is a crucial factor in determining a planet's ability to retain an atmosphere. Higher surface gravity can help a planet hold onto heavier gases, making it easier to maintain a thicker atmosphere. Conversely, lower surface gravity may lead to atmospheric escape, particularly for lighter gases, resulting in a thinner atmosphere. This relationship influences a planet's climate, potential for habitability, and the presence of liquid water.
