What kind of gravity does Saturn have?
At the surface, it's about the same as the Earth's . You get a bit of variation in the value given, but, at the equator, it's about 1.065 times the Earth's. It is about 0.92 times the Earth's gravity, if you take into account the effect of the planet's rotation.
Why is the earth gravity stronger than the moon gravity?
Gravity is a force created by and felt by mass. All massive objects have a force of gravity that is directly proportional to the amount of mass within the object. The gravitational constant is a coefficient that relates exactly how much mass = how much gravity. Given that the moon is less massive than the Earth, we would expect less gravity. Similarly, Jupiter has much more mass than the Earth and also has more gravity.
What is the gravital pull of Saturn?
You will find a variation in the answers given for this even by reliable sources. The "surface" gravity of Saturn is certainly similar to Earth's. The value I normally use is: about 1.06 times Earth's surface gravity.
Explain how a larger planet could have a smaller surface face gravity then a smaller planet or why it could not?
The strength of gravity from a given object is directly proportional to the object's mass and inversely proportional to the square of the distance from the center of mass. So, if we double an object's mass the gravity is double. If we triple the mass the gravity is tripled. By contrast if we double the distance we end up with one quarter the gravity. If we triple the distance we end up with only one ninth the gravity.The formula for the strength of gravity is: g=G*M/r^2"G" is the Newtonian gravitational constant, "M" is the mass of the object, and "r" is the distance tot he center of mass.In the case of the surface gravity of a planet, the distance to the center of mass is the planet's radius. So if two planets have the same mass but are of different sizes, the larger planet will actually have weaker surface gravity. In most cases a larger planet will have a greater mass than a smaller one, but not always as planets vary in density. Event if the larger planet is more massive, the larger size can still result in weaker gravity.A perfect example would be a comparison between Earth and Uranus. Uranus is about 4 times the radius and about 14.5 times the mass of Earth. From these figures we find that the gravity on Uranus is 0.906 times or 90.6% of Earth's surface gravity.
Is the center of the earth hot or cold?
nothing
How do we find the center of gravity of a given aged?
You can use plumb lines to find the center of gravity of an object.
Can a body rotate about its center of gravity under the action of its gravity give reasons?
A body can rotate about its center of gravity due to external forces, but not due to its own gravity. Use a free body diagram If no unbalanced forces exist, or a couple moment, then there will not be any forces to cause the body to rotate btw, the earth does not rotate because of its own gravity, the earth rotates because of the external forces given to the body of earth when the solar system formed. Don't quote me on it but this is my understanding I'm currently taking Statics and Dynamics in Engineering (Physics)
How does earth's gravity work?
Gravity is an attractive force that is exerted by all matter. Any two objects with mass will be attracted to one another. The greater the mass of the object, the stronger its gravity at any given distance. Most objects do not have enough mass for their gravity to be noticeable, but Earth does, as do all planets. Any object near Earth will be pulled in the direction of Earth's center.
What is the time period of simple pendulum at center of earth?
i think it is infinite because acceleration due to gravity at the center of the earth is zero and time period of the simple pendulum is given by 2*3.14*sqrt(l/g)....
How does the acceleration of gravity depend on it's distance from the center of the Earth?
acceleration due to gravity is given by, g=GM/R2 Hence distance from the earth increases g decreases and viceversa. So g at poles is greater than g at equator.
Is gravity canceled closer to the earth or moon?
Earth-Moon GravityThe point at which the gravity of the Earth is counterbalanced by the gravity of the Moon is much closer to the Moon. The stronger gravity of Earth has a greater effect for any given distance.Independent GravityThe Earth's gravity is greater than the Moon's, so the Moon would have a lower escape velocity and a lower possible orbit, even neglecting the fact that it has no atmosphere. Gravity diminishes with distance, so the effective gravity at any given distance from the Moon will be much less than the effective gravity at that distance from the Earth.
