Gravity Force Inside a Spherical Shell - GSU

A sphericallysymmetricbody affects external objects gravitationally as though all of its masswere concentrated at a pointat its center. If the body is a spherically symmetric shell (i.e., a hollow ball), no net gravitational forceis exerted by the shell on any object inside, regardless of the object's location within the shell. See more In classical mechanics, the shell theorem gives gravitational simplifications that can be applied to objects inside or outside a spherically symmetrical body. This theorem has particular application to astronomy. Isaac Newton proved … See more A solid, spherically symmetric body can be modeled as an infinite number of concentric, infinitesimally thin spherical shells. If one of these shells can be treated as a point mass, … See more It is natural to ask whether the converse of the shell theorem is true, namely whether the result of the theorem implies the law of universal … See more An analogue for shell theorem exists in general relativity (GR).

WebAccording to Equation ( 898 ), the gravitational potential outside a uniform sphere of mass is the same as that generated by a point mass located at the sphere's center. It turns out that this is a general result for any finite spherically symmetric mass distribution. http://www.astro.yale.edu/vdbosch/lecture2.pdf

WebIn the case of a spherically symmetric mass distribution we can conclude (by using a spherical Gaussian surface) that the field strength at a distance r from the center is inward with a magnitude of G / r2 times only the total mass within a smaller distance than r. All the mass at a greater distance than r from the center has no resultant effect.
