... Example: Two identical disks have a string coiled around them. The string is pulled with a constant force F over a distance d. In one case, the disk rolls without slipping on a table. In the other case, the disk rotates about its axis (like a pulley). Compare the final angular speeds of the disks. ...

... In a real system, electrons are not really free, they interact with the ions that are hopping in place (phonon) and they interact with imperfections in the crystal. A more appropriate model consists in assuming that these electrons are free to accelerate just during a time t= after which they just ...
