What is the value of G 9.8 or 10?
The Value of g Depends on Location
Location | Distance from Earth’s center (m) | Value of g (m/s2) |
---|---|---|
Earth’s surface | 6.38 x 106 m | 9.8 |
1000 km above surface | 7.38 x 106 m | 7.33 |
2000 km above surface | 8.38 x 106 m | 5.68 |
3000 km above surface | 9.38 x 106 m | 4.53 |
Why is 9.81 the accepted value for gravity?
A: Gravity (or the acceleration due to gravity) is 9.81 meters per second squared, on the surface of Earth, because of the size of Earth and the distance we are on its surface from its center. Throughout space, gravity actually is constant. …
Is gravity constant regardless of height?
A gravity force acts on an object regardless of whether it is moving or not moving. In everyday situations, the size of the gravity force on something does not change significantly as it rises above the Earth. The size of the gravity force at an altitude of 200km is still about 94\% of what it was at sea level.)
Why does the value of g vary from place to place Class 9?
The gravitational potential at the surface of Earth is due mainly to the mass and rotation of Earth, but there are also small contributions from the distant Sun and Moon. As Earth rotates, those small contributions at any one place vary with time, and so the local value of g varies slightly.
How is gravity value calculated?
G is the universal gravitational constant, G = 6.674 x 10-11 m3 kg-1 s-2. M is the mass of the body measured using kg….The Table Below Shows the Value of g at Various Locations from Earth’s Center.
Location | Distance from Earth’s Center(m) | Value of g (m/s2) |
---|---|---|
50000 km above surface | 5.64 x 107 m | 0.13 |
