Where does the center of gravity of the atmosphere of the earth lies?
Since the atmosphere is more or less symmetric, its center of mass (center of gravity) gravity must be quite close to Earth's center.
How does gravity affect the earths sky?
The sky is air and gravity keeps the air close to the ground so we can breeth it in .
Why does air pressure drop as you move away from the earths surface?
In simple terms... gravity ! Gravity is holding the air close to the surface of the Earth. The further away you are from the surface - the lower the gravity - and thus the lower the air pressure.
How do you minimise the drift on instrument?
To minimize the drift on instrument you will want to lay it in the center of low gravity and close t the table surface. Which makes the base dimensions large compared to the height of the center gravity.
According to the law of gravitation how does the force of gravity relate to an objects distance from earths center?
F=G(m*M/r^2). If the object is close to the earth's surface then F=mg (where g=9.81 (m/s^2)) is a good approximation.
What is earth gravity in decimals?
There is no fixed figure for earths gravity.The effect of earths mass (or gravity) depends on its mass and how close you are to it.the gravitational force (f) on an object (by the earths gravity) can be calculated by:.f (newtons) = (G * m1 * m2) / d^2.key:m1 = earths mass (5.974 * 10^24 kg)m2 = objects mass (kg)d = distance between their centres of gravity (metres)G = newtons gravitational constant (6.672 * 10^-11).notes:the force on the object is equal to the reaction force on the earth.
Why is air pressure lower at the top of mountain than at the bottom of a mountain?
In one word - gravity ! Gravity hold the atmosphere close to the surface of the Earth. The higher you are off the ground - the lower the gravitational effects.
Why does a pin attracted by a magnet move upwards and not downwards towards the earth's gravitational pull?
because, the strength of the metal magnet is stronger then that of the earths gravity when held at a close distance.
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.)
How does the gravity affect the atmopshere?
It (gravity) keeps it (atmosphere) close to Earth.
Why is there still gravity when you close your mouth?
Gravity never stops pulling you towards the centre of the Earth even when you close your mouth.
Why do the Moon's gravity have a greater effect on earths ocean tides than the suns gravity?
Even though the suns gravitational pull is stronger than the moons and does infact effect the tides slightly, the moon is close enough to pull the tides more than the sun. Its all distance related.
