Question

When a sarellite in a circular orbit around the earth enters the atmospheric region it encounters small air resistance to.its motion then trends of Kinetic energy and angular momentum will be?

Answer 1

Kinetic energy will increase as velocity will be increasing while descending to earth in its atmosphere.(may be it will be brust into pieces before touching earth surface)
Angular momentum is MVR and it depends on both velocity and distance from the earth.So distance will decrease but velocity will increase while descending.

Nothing can be said about angular momentum,probably it will increase too as earth's gravitational force will creat centripetal acceleration.

Thanks.
