English: So, if there is a given orbit like this, there is a distance r₁ smaller distance r₂ and when I calculate for example, p_(r)dr, I will be going from r₁ to r₂ p_(r)dr plus to complete the full period I will be coming from r₂ to r₁ p_(r)dr and that would give me both integrals give me the same answer because the symmetry and therefore, this is nothing, but On the other hand, for central force like V(r) =  − k/r, p_(ϕ)which is $mr^{2}{\phi\ \dot{}}^{}$which is nothing, but the angular momentum is conserved this quantity is conserved and therefore, p_(ϕ)is going to be constant for a central force.
Telugu: ఇచ్చిన కక్ష్య ఈ విధంగా ఉంటే, దూరం r₁ స్వల్ప దూరం, r₂ దూరం ఉంటుంది మరియు నేను లెక్కించినప్పుడు ఉదాహరణకు, p_(r)dr, = p_(r)dr + p_(r)dr సమరూపత కారణంగా రెండు ఇంటిగ్రల్ విలువలు ఒకే సమాధానం ఇస్తుంది.
