Question

Answer 1

The freewheel cassette (the gears) are spining free, but the bearings on your wheel inside the hub are most likely worn out.  You will have to replace the bearings and re-grease them to make sure that the wheel spins smoothly again.  See Sheldon Brown's article on overhauling hubs for more information.

Answer 2

It is not the bearings as previously mentioned.

The cassette can be completely removed and the ratcheting mechanism in the hub should still catch in the forward direction.  You may have a broken, or rusted frozen dog that makes the clicking noise when you coast or pedal backwards.

If it is not a cassette style, but rather an older free wheel style the same diagnosis, just a different way to remove the gears.  Both are discussed and illustrated at the above link.

Answer 3

that means its broken and u need a new one, i think u need a special tool to remove it too, or maybe just a s***w driver and a hammer
