Gravity is working to pull the falling feather down to the ground.
The obvious is gravity. Wind creates both lift and rotation, both of which create inertia. If the feather tilts, it will also be subject to acceleration and/or velocity loss.
no force act on it
Buoyant force viscous force
Gravity and air resistance.
gravity and air resistance both act on a free falling object.

An input force is what force you act upon a machine. The output is what it does for you in return.
Gravity and air resistance.
Yes

Yes. Gravity. Air resistance (friction again).
Friction always acts in a direction opposing the motion of an object.
A unbalanced force must act upon it. ;)
Forces of gravity ( gravitational force) pulls the meteor to earth
Either an alarm clock or a Force (preferibly not the dark side, as that never turns out well).
