My brother just left for Chicago T_T. I won't see him 'till May (hopefully). I'm gonna miss the weeklong no-leftover-dinners/lunches :P. So last weekend, to celebrate my birthday and my brother's spring break with his friend, we went to a luau at Paradise Cove (by Ko'olina). We had a couple of hours to kill, so we wandered around trying all the "ancient Hawaiian" games and activities. One of the activities was swinging around poi balls since they were used as weapons, and now as entertainment. Needless to say, we failed. Horribly.
What does this have to do with Physics? Well, first off, there was tension in the ropes due to the weight of the balls. When we (attempted) to swing them in a circle, there was an acceleration directed radially inward. Since it was in a vertical circle, gravity also took its toll, making it slow down as the ball when upwards and quickening its speed when it went downwards. It wasn't helpful that we had to try with two balls in the same hand, going in opposite directions. Darn you, gravity, and probably a dozen other factors that caused me to be pummeled by those things every five seconds.
Sorry that this week's blog is so lame. I'm currently baking and my English grade depends on it.
Yay for chocolate cake! Boo for it failing on me!!!
