SCRAMBLED EGGS?


This week in class we pono and i had to build a device that could keep an egg safe while dropping it from the top of Akahi (super high). Our egg drop device consisted of a very complicated design. We figured that the cone would be a perfect device. The cone would be bottom heavy cause there was more paper at the bottom.The egg would sit nicely on a bed of feathers and tissue paper. Finally the four wings would keep the cone up right and slow the decent. Well, we thought wrong.! As soon as the wind caught our device, the cone flipped and landed egg first. I think that if the cone were not as top heavy, we would have had a better chance of survival.

PONO "THE HAMMAH" CHOY


This week in physics we learned aboutLLinear Momentum on one axis. The si unit for momentum is kg x m/s. This is because MASS X VELOCITY = MOMENTUM. Momentum in is equal to momentum out. This is a picture of Pono "The Hammah" Choy laying the lick on number nine from punahou. (they are not even good enough to get a capital p) Pono is about the same mass as number 9 but, because he has more momentum, he runs right through him like a hot knife through butter. Pono has a much higher velocity which causes him to have a much higher momentum. Momentum helps a lot when playing defense!!

CAR CRASH!!


This week in physics we experimented using car crashes. It just so happend's  that my uncle got into a car crash the other day. When he told me i thought of the lab immediately. This was different from the lab because when my uncle was hit he was stepping on his brake so his car didnt move in the oppisite direction. It just skidded forward unlike the car in the lab that bounced in the oppisite direction. It was like the cars that got stuck together with the velcrow. The brakes added friction and caused the car to not move as much. Finally this car got way more messed up then the cars in the lab.

I THINK I KNOW MOMENTUM


Our next subject in Physics is about momentum. Before i look it up on google i thought about my two dogs. The small dog is Cissy and the bigger dog is her puppy Champ. In my house there are wood floors and my dogs are house dogs. Cissy's mass is small compared to Champs mass. When the dogs run in the house Cissy can stop quickly, Champ on the other hand goes sliding across the floor every time. I think this is because his mass is greater which means he has a greater momentum.  Momentum is the product of the mass and velocity of a specific object according to google.
