What is the center of gravity for a spherical object?
The center of gravity for a spherical object is located at the exact center of the sphere. This point is equidistant from all points on the surface of the sphere, making it the point where the force of gravity can be considered to act on the object.
What is the accelaration gravity of the center of Earth Surface?
At the earth's center, the acceleration/force of gravity is theoretically zero.(At least the force of gravity between the earth and an object at its center. There's still the gravitational forcesbetween the object and everything else ... the sun, moon, stars, etc.)
What is residual gravity?
Residual gravity is the effective gravity that exists between the earth-moon or the earth-sun combination. When two heavenly bodies interact such as the earth and the sun there is a difference in mass which causes a residual gravity to exist in the space between them. This residual gravity is responsible for the earth's orbit.
What is the effect of shape of earth on acceleration due to gravity?
Earth is slowly flattening out. Our planet used to be almost exactly spherical when it just formed, but over time it squashed out. You can test this by taking a piece of salt dough and rolling it into a ball. Then, put it inside a pail with a long string handle. Whirl the pail around your head for a while, then examine the salt dough. It will be flattened. To make salt dough: Mix salt, flour, and water.
How does the moon's gravity compare to Earth's gravity?
The moon's gravity is about 1/6th of Earth's gravity.
Is your earth spherical if yes then how?
Gravity
What fore gave earth its spherical shape?
Gravity.
Is the earth really spherical?
The Earth is almost spherical. It's slightly squashed, or oblate.
Why is the flame spherical in space?
In space, flames become spherical due to a lack of gravity to pull the flames upwards. The absence of gravity causes the flame to burn in all directions uniformly, creating a spherical shape. This phenomenon is known as a "cool flame" and is different from flames on Earth, which are affected by gravity.
Why do you say earth is spherical?
The earth is spherical because the gravity pulls all the sides towards the core and its equal gravitational pull all round so this ceates a speherical like shape.
What planets have a surface gravity almost the same as earth?
earth
Why is earth spherical in shape?
That is due to gravity. Any large deviation from a spherical shape - such as a mountain that is more than a few kilometers high - would be squashed down by gravity.
What is Venus's gravity?
almost the same to earth
Why doesn't the gravity of the sun and moon affect us?
It does. Earth is moved by the gravity of the sun and, to a lesser degree the moon. We are move by almost the same amount and so we move with Earth. Since Earth's surface is our point of reference and we are moving with it, we don't notice it. We observe the effects of the gravity of the sun and moon in the tides.
Why are all the layers of the earth spherical?
Because the earth is held together by gravity and also because if they were not new plates would not form.
Is there gravity on Mars less earth?
Yes. The effects of gravety on Mars are less than on Earth. Mars has 37.6% of Earth's gravity.
Why does Eros have an irregular shape instead of a spherical shape?
Jupiter's gravity It is not massive enough to pull itself into a spherical shape like something the size of the moon or Earth.
