Is there gravity at the centre of the earth
WitrynaFor the rotating Earth, centripetal force is supplied by the gravitational force towards Earth's center.) If Earth was a perfect, rigid sphere, the ocean would be 20 km deeper at the equator than at the poles. ... by the extra gravitational force there (this is referred to as “effective gravity”). The mathematical expression for centrifugal ... Witryna9 kwi 2024 · If gravity is the result of space flowing into a massive object (9.8 m/ sec on earth ) then does it accumulate there. Many explanations out there for gravity. One that I saw a few months ago explained that our gravity hete on earth is space moving toward the center of the earth, and we should be falling to the center of earth at a rate of …

WitrynaAs a result, the gravitational force at the center of anybody will be zero. Because we know from Newton's law that F = m g. Since an object's mass m can never be zero. As a result, when F = 0, gravity ( g) must be 0. Thus, the value of g is zero at the center of the Earth. Suggest Corrections 8 Similar questions Q.
