Everything that has mass (or rather everything that has energy) constantly exerts a gravitational pull on everything else (that has energy). Objects do not deplete some energy source to do this, it constantly happens. This does not violate conservation of energy by the way, because it only costs energy if the other object actually has a change in speed because of the gravitational influence of the first object.
What else can I help you with?
Which source of gravity is maintaining all four satellites around the earth?
Satellites of the Earth are held in their orbits by the Earth's gravity. That includes the Moon and all the artificial satellites etc. that are up there.
What force pulls an objects toward the center of the earth?
Gravity is the force that pulls objects towards the center of the Earth. This force is responsible for keeping us grounded and maintaining the orbits of celestial bodies around planets.
How does the moon crontrol gravity on earth?
No. The earth has its own gravity. The lunar gravity causes tides on earth, but does not control earth's gravity.
What is the role of gravity in maintaining an atmoshere?
It is essential: no gravity - no atmosphere.
What is the gravity on Mars compared to earth?
The gravity of Earth is 2.6 times that of Mars.Mars's gravity is 38% of Earth's gravity.
How does the moon's gravity compare to Earth's gravity?
The moon's gravity is about 1/6th of Earth's gravity.
On what day will the earth have no gravity?
Earth will always have gravity for gravity is a result of mass.
What is Charon's gravity compared to Earth's gravity?
The gravity of Charon is about 3% that of Earth.
What is the math for mercury gravity compared to earth?
mercury gravity: earth gravity
Is the gravity on earth 1?
Earth's gravity is 1g.
Has earth ever had gravity?
The earth currently has gravity.
Were on earth is their no gravity?
Well on earth everywhere this is gravity. but once you leave earth there is no more gravity ----------------------------------------------------------------------------------------------- No, gravity is present through out all space. When you leave the Earth and go into orbit round it, it APPEARS that there is no gravity, but gravity is causing you to orbit the Earth. You do not feel this gravity because you are in free fall.
