Gravitational force inside earth formula 328652-How to calculate earth gravity

イメージ
G = Gravitational constant = 667x1011m3kg^1s^2 This constant is very small ans is testimony to how weak the force of gravity really is Compare this with the equivalent electrostatic force equation between two charges (Coulomb's law) whos constant is 10^ times largerA classic problem in mechanics is the calculation of the gravity force that would be experienced by a mass m that was attracted by a uniform spherical shell of mass M The law of gravityapplies, but calculus must be used to account for the fact that the mass is distributed over the surface of a sphere The problem is envisioned as dividing an infinitesemally thin spherical shell of density σThe 98 m/s^2 is the acceleration of an object due to gravity at sea level on earth You get this value from the Law of Universal Gravitation Force = m*a = G (M*m)/r^2 Here you use the radius of the earth for r, the distance to sea level from the center of the earth, and M is the mass of the earth Universal Law Of Gravitation How to calc...
