In space when something is put in motion it stays in motion true? If it is true can this this be used in space?

On the space ship can you have a vent to let in vacuum and a generator inside of it to produce power? Have the vent closed until you get into space, then open it and start the generator spinning to create energy. Will it stay moving in the vacuum and produce energy?In space when something is put in motion it stays in motion true? If it is true can this this be used in space?
i suppose what you propose is a electricity generator that once you start woulnd stop, however the kinetic energy would transform into electricity and the generator would stopIn space when something is put in motion it stays in motion true? If it is true can this this be used in space?
The whole thing is based on friction and gravity.





In space, there is no air, so there is no friction between the space ship and ';air';, so there is nothing to stop the space ship from moving. It might change its direction because of gravity of a near-by star or planet, but it would not stop moving unless it HIT the planet (or its atmosphere). it would also speed up as it got closer and closer to a star or planet. in fact, if you can figure your orbit JUST RIGHT, you can get a ';slingshot'; effect, using a planet's gravity to increase your speed without going into orbit.





But vacuum is nothingness. you cannot 'let in'; a vacuum. you ';let out'; everything else!





Vacuum has nothing to do with a generator. The BIGGEST source of friction in a generator is in the bearings and electrical contacts. Vacuum will NOT affect these. So the generator WILL stop turning. There is NO SUCH THING as Perpetual Motion. There is ALWAYS some sort of friction, somewhere in the system, and eventually ALL systems WILL stop moving.





Even the expansion of the universe will, someday, stop, due to gravitational attraction slowing things down.
No. The reason generators and turbine's spin on earth is because something (air, water, etc) is passing over the fins. The force of the air/water particles cause the fin to move.


The particles will be moving because of a pressure gradient (higher density to lower density).





In space, it is a vacuum (which mean's nothing, not even air is there), so there aren't any particles to push on the generator's fins. So it won't spin
No, because a vacuum is not something that enters. A vacuum has to fill up. If there is no more material that can fill it up, the process stops.





It is true that an object that moves will keep moving, unless affected by an outside force (inertia). In space, there are relatively few of these forces that are powerful enough. Gravity can be overcome when the distance between the object and the closest large body is far enough away.
yes it should stay and it will produce energy

This will not work, a vacuum creates suction by moving air, the ships air suuply would be used up.
