Are Linear and Angular Momentum Conserved for a Satellite?

The video tutorial discusses the conservation of linear and angular momentum for a satellite in an elliptical orbit. It explains that linear momentum is not conserved due to the gravitational force acting on the satellite. However, angular momentum is conserved because the net external torque is zero when considering the center of mass of the primary as the axis of rotation. The tutorial emphasizes the importance of defining the axis of rotation and concludes with insights on elliptical and circular orbits.
