Outside a shell: The last part of this section goes back to derive the solid sphere result. Made it a subsection and made clear that the solid sphere result is being re-derived.
Changing short description from "Statement on the gravitational attraction of spherical bodies." to "Statement on the gravitational attraction of spherical bodies"
Line 1:
{{shortShort description|Statement on the gravitational attraction of spherical bodies.}}
In [[classical mechanics]], the '''shell theorem''' gives [[gravitational]] simplifications that can be applied to objects inside or outside a spherically [[symmetry|symmetrical]] body. This theorem has particular application to [[astronomy]].
