Satellites in near-earth orbit experience a very slight drag due to the extremely thin upper atmosphere. These satellites slowly

but surely spiral inward, where they finally burn up as they reach the thicker lower levels of the atmosphere. The radius decreases so slowly that you can consider the satellite to have a circular orbit at all times. As a satellite spirals inward, does it speed up, slow down, or maintain the same speed?

According to my research, a satellite in a circular Earth orbit is subject to a very tiny constant friction force, due to the atmosphere. As it spirals inward, it slowly decreases its orbital radius.
So as long as a satellite moves in a circular orbit, it's velocity is inversely proportionate to the square root of the orbital radius-it speeds up as it spirals inward. I hope my answer proves of some help to you.

How does the mass of an object affect its acceleration during free fall
ira [324]

The mass of an object has no effect whatsoever on the object's
acceleration during free-fall.  If there is no air resistance to interfere
with the natural effects of gravity, then a feather and a battleship ...
dropped at the same time ... fall together, and hit the ground at the
same time.
