So assuming the rotor is spinning forever regardless of where I take it in the universe it will always point in the exact direction that I started spinning it at?
If that is the case then how do things which use gyroscopes to determine direction compensate for the earth's spin and orbit?
I know when spinning a gyroscope will resist change in orientation so that the rotor is still pointing in the same direction.
But, is that direction with respect to earth's center of gravity or is it an "absolute direction".
So, if I point a gyroscope upwards and spin the rotor and I go...
Sorry guys but I need someone to clear up what I consider something I may have a misconception about.
In my understanding a magnet or magnetic forces, can do work yet expend no energy. Is this correct? And if so is there a law I probably havn't learnt yet? Is it one of those things noone can...
Not sure if there is any way you can get the discription more dumbed down then that. Mass is how much "stuff" there is there. There that is my best effort if you don't understand it then I don't know what to say.
Obviously, you count it, and the amount of it is reprisented as Mass.
