Dam ok blog 10

so ok i guess i missed this blog my bad Mr. Kohara. so in class we are studying about gravity and the conservation of energy and kinetic and potential energy and just today in fact i saw brother drop his jello that he was eating on the ground. As it fell i first thought ohh no, but when it hit the ground i realized that i could possibly use jello for our egg drop experiment. Because it is soft and has give but it also is sprining. But im not to sure weather or not you would consider jello as a liquid or a solid. I mean it was cool to see it fall and not break. I mean it fell from about 4 feet and didnt break or anything so i mean it could possibly work but we will just have to watch and see. Because it slowly would stop the eggs because it is soft and would be a cuzhion but hard enough that it would explode on impact. Or at least it dint from my brothers mouth.

Blog 12

The other day was driving to my gf's house and it had just been raining and when it stoped i looked ahead up the road and i saw a double rainbow. It was sick so i pulled over on the road and took a pic of it. A rainbow is caused when light refracts off the inside of the rain drops at different heights to create a rainbow a double rainbow is caused by the same principle but its just light is hitting the rain drops in more than one place.

So the other day i was driving home and this park by my house always has these kids sliding down this hill on card bpard boxes. So i stoped at the trafic light and was watching them. I notcied that the small kids sometimes didnt go and the really big kids held the box in place so it didnt move. And this got me thinking of physics and how momentum and force and friction all play a major part in our society. That no matter what we do physics has some sort of impact. The friction caused by the grass and the weight of the kids sometimes had a great effect either not letting the kid move or by gaining to much speed cuz there was not enough friction. I think we should all go box sliding its super fun and involves alot of physics.
