When a satellite in a circular orbit around the earth enters the atmospheric region it encounters small air resistance to its motion. then (1) kinetic energy increases (2) angular momentum decreases {i saw an answer where the increase in velocity was justified by decrease in angular momentum (how can we do that if its angular momentum isnt conserved)}

  • $\begingroup$ Hmmm... I'm not sure what you are asking about. The decrease in angular momentum just shows that its angular momentum isn't conserved, and the angular momentum does not need to be conserved here due to the air resistance. Could you make your question more clear? $\endgroup$ – pinchun Feb 7 at 10:04
