KnowraCentral forceLinked fromLinked fromThe 7 pages that link to Central force, each with the reason it gives.All 7Related 4Narrower topic 3Two-body problemNarrower topic: Newtonian gravity is central, so angular momentum is conserved.Conservation of angular momentumRelated: A central force produces no torque about its center, so angular momentum is conserved.Reduced massRelated: When the interaction is central, the reduced-mass particle moves in a central potential.Spherical coordinate systemRelated: Its radial geometry makes spherical coordinates natural for describing motion.Kepler's second lawRelated: A central force has zero torque about its center, producing the conserved angular momentum behind the law.Kepler's first lawNarrower topic: The Sun’s idealized gravitational pull is central.Newton's theorem of revolving orbitsNarrower topic: The theorem applies to motion under forces aimed at a center.
