www.damtp.cam.ac.ukWe already saw in Section 2.2.2 that angular momentum is conserved in a central potential. The proof is straightforward: dL dt = mx⇥x¨ = x⇥rV =0 where the final equality follows because rV is parallel to x. The conservation of angular momentum has an important consequence: all motion takes place in a plane.
