yes
NO, airplanes have to keep moving in the air.
an object that is moving will keep moving until something stops it
Air flow. They help to keep air moving to your return air grill.
Resistance from air and friction.
No. It takes a force to put something in motion, and it takes force to stop it. To keep it moving requires zero force. If there is no opposing friction force, it will continue moving forever. If you can significantly reduce the friction, a small force can keep an object moving - just enough to counteract the force of friction.No. It takes a force to put something in motion, and it takes force to stop it.

Because of something called inertia. Things that are moving likes to keep moving, and things that aren't moving likes to stay put. For anything to change from moving to stationary, or stationary to moving, there has to be an outside force acting on them.

Yes, air has inertia which is the tendency of a moving object to keep moving in a straight line unless acted upon by an external force. This property of air is why it takes time for air to start moving or stop moving when a force is applied to it.

Try drinking caffiene. Do something to keep you busy and moving around.
To hold something in place and keep it from moving. Plumbers use them when cutting pipes for example.
