centripetal motion:

angular acceleration and velocity:
http://en.wikipedia.org/wiki/Angular_acceleration
a simple comparison of centrpetal motion and angular acceleration is to grab a beer, open it and hold it in your fully extended arm as you spin around faster and faster, watching your beer dissapear in an angular acceleration away from your centrpetal motion. and effect sometimes called centifugal force.
