The Short Answer
The others appear to move because the earth is spinning on its axis. Directly above either of the poles of that axis, a star will appear to barely move at all, but other stars will trace circles around it through the night. You can take some cool long exposure photographs by pointing your camera at celestial north and waiting. Stars will smear out into concentric circles around celestial north.
