Earth gravity at altitude
WebApr 6, 2024 · The gravity of the earth is caused by all of its mass. Its whole mass exerts a cumulative gravitational force on the entire mass of your body. That is what gives you heft. And if you were on a planet with a lower mass than earth, you would weigh less. The value of gravity on the surface of earth is 9.8 m/s2. Webt = time (s) The acceleration of gravity is stronger at the poles than at equator and the equation above can be modified to. t = (2 s / ag)1/2. The time for an object at level 1 m to hit the ground on the pole can be …

WebDec 28, 2024 · In Low Earth Orbit (i.e. things orbiting Earth), they are in nearly the same gravitational field as we are. For example, the ISS orbits roughly 400 km above the Earth, which is only 400/6378 $\sim$ 6.3 % farther from the center of the Earth than the surface. Since gravity scales as $1/r^2$ that means at that altitude, gravity is still about 88% ... Web(3)Various observations in different altitude, cross-distribution, and land-sea coexisting cases can be directly employed to estimate the full element models of gravity field without reduction ...
