The Chun Girls:Michelle, Me, San, Kristi, Katie, and Jamie
The picture above is of my girl cousins on the Chun side. When we're not at my popo's house, we go to Chinese restaurants--since we are Chinese. ^.^ Anyways, I was thinking what I could put in this week that pertains to the stuff we are currently learning. Then I was watching the food channel while i was thinking and then i was thinking of pe king duck and all that good stuff and then BAM! it came to me. THOSE LAZY SUSANS (those circular turning tables) AT CHINESE RESTAURANTS! It is a good thing that the food does not fly off when you spin those tables. How is that so? Well the friction of the table and food dishes help. and since you probably dont put that much velocity to the spin, the centripetal force is not that great so the friction ends up overcoming that force, thus the food stays on the table. What if there was a great velocity, do you think the food dishes would fly off the table? Maybe you should try it out...HAHA!

genius! i never even thought of that!
hi steph! :)
i like the picture
& the very physicsy blog
like katie said, me too!
ok, but i can't let the bit of misinformation go by... friction doesn't overcome the centripetal force! rather, it is the force that provides the needed push to keep the plates moving in a circular path. i.e, friction *is* the centripetal force.
