Gauss gravity law
WebOct 2, 2016 · $\begingroup$ While it's healthy to know these derivations, you should keep in mind that Gauss's law is more general than Coulomb's law. Coulomb's law is only true if the charges are stationary, there are no changing magnetic fields, etc. But Gauss's law is true under all circumstances. WebNewton's law of gravitation, Gauss' law. The gravitational force and potential energy. Problem: Consider a rotating spherical planet. The speed of a point on its equator is V. Particles near the surface of the planet accelerate downward (towards the center of the planet) with acceleration g' = ½g, where g is the downward acceleration of particles at …

WebApr 30, 2024 · $\begingroup$ @21joanna12 I think Gauss's law as applied to gravity is essential for solving this problem efficiently. For instance, it took Issac Newton many pages of tedious calculus to show that a hollow sphere has no gravitational field within it, while with Gauss's law the proof is 1 maybe 2 lines. $\endgroup$ – WebStill, a physical way to state Gauss's law is: "for a surface with no enclosed mass, the net gravitational flux through the surface is zero." Example: gravity far from an arbitrary source Now let's see the practical use of the …
