Rotational motion of a cylinder

  1. Sep 23, 2009 #1
    ok im not sure what this kind of motion is called but it is caused when a cylinder, a AA battery lets say, is liying on a flat smooth surface and a torque is applied to one end which causes the battery to stand up and spin on one of its ends. ive been looking for a name or a few details about this motion, i want to do a little research.

    thanks in advance. - Tyson

    im fairly certain its the same motion as when you spin a coin on a table.

    Hi there!
    The force that govern what you are saying is called precession. Precession can be seen when you ride a bicycle. It is this precession force that keeps you standing on 2 wheels. I don't know much about the principle of precession. But precession is the main character in a gyroscope.
    Thanks
