Leyna Jean’s Physics Blog.

Last blog. I promised myself I wouldn’t forget. But I say that most weeks. Physics is not over yet. I hope I didn’t lose my notecard. But I’m planning on coming on Wednesday. I wonder what y0u guys did on Friday. The waterpark made my feet sore, but at least i dont think i got sunburned. Which is good.

This is my new favorite picture
I LOVEEEE physics. Thursday John was doing center of mass on the table.
But I couldn’t because I was wearing a skirt. But I remembered what center of mass was.
Which I don’t think is relevant anymore. But that’s okay!

Okay. So this is like the second to the last blog.
After that, I won’t have the chance to forget to
write in it anymore.  Honestly, I’m really not
sure why I’m so forgetful. But I’m doing pretty
bad on the quizzes. Actually, I’m sure you already
know that. But I’m almost really sad that physics
is going to be over since our class turned out
to be way better than I thought it would be.
Especially because I have a really cool lab partner
that shakes hands funny. But seriously, I think
about physics stuff quite a bit. The

Hi. Okay so I don’t know what I want to write about this week yet. Maybe I can use this

Something like, if I had a converging lens, I probably could have gotten all of Vlad in the picture. Or I could have gotten more of my dress. Or at the right angle, maybe even my shoes. But if we were looking in a mirror, the mirror would only have to be at half of our body lengths though. I got gel nails for prom. I really like typing with them It feels really cool.

Peephole 200 degrees. So recently we’ve been learning about
converging and diverging lenses. One is thick in the center and thinner
on the outside and the other is thick on the outside and thiner on the
inside. One magnifies and the other minifies. And a lot of it depends on
distance of the object from the focal point. There is a focal point on
one side of the lens, which is the object side which is the side the object
is on and the other side of the lens which is the other side which is the
side that the object is not on. Anyway, the focal point is the same distance
away from the lens on each side. Remember that.

Vlad, thanks for reminding me about this. Okay. So. Here it is.
Oh. Before I forget, Doc, I’m actually going to be taking the test tomorrow during class and not during period 6.
Yeah. Idk. I got the schedule messed up and I thought periods 1 and 2 were before lunch for some reason. I don’t know. Anyway! This week I was going to blog about Rachelle swinging. We were talking about swings when we were doing the video projects i think.

this is Rachelle on a swing. Circular motion, go.

to post this week.
Okay so today I went to go see The Soloist which is this movie about a homeless musician, played by Jamie Foxx, and a reporter, played by Robert Downey, Jr., who tells the story of the homeless man. Initially, I was going to write this blog about Rachelle swinging in the park, but I think I’ll write about that next week. If I remember. Anyway, so the movie deals a lot with music and the homeless man playing a cello and a two string violin. So when I saw him playing the violin with two strings, I thought about the erhu after I thought about this physics blog. I mean, it didn’t look like an erhu or anything, but I figured I could relate it somehow. And they also did this close up of the cello strings and the bow against it and I totally thought about the vibrations and stuff and how that makes sound. Haha.

compare.

So lately we’ve been talking about generators and motors. And basically the difference between the two is the fact that one produces energy and the other needs energy to work. That made me think of a car engine. So basically, according to my own knowledge, a car engine works like intake, compression, explosion, and exhaust. And that’s basically a motor. The intake is like the air and the compression and the explosion is how the energy for the car is produced.

This is what failure looks like. It includes one battery, one piece of copper wiring, two paper clips, one magnet and a lot of tape. In actuality, we used like two batteries, 4 lengths of copper, eighteen paper clips, eighteen bazillion pieces of tape and sometimes two magnets. But this was our final model that almost almost worked except for Micah. But that’s okay. So the elections travel from the negative terminal of the battery and travel through the paper clip and onto the piece of copper which we had to sand and with the help of the magnetic field from the magnet, the copper starts to spin as the electrons go all crazy in the magnetic field created by the magnet. and I know there is a better way to say that. And I will figure it out. Soon.

So on Friday we had to take this assessment test to see where America ranked against the rest of the countries in the world. Somehow our grade was magically selected to take this test.  Also some unfortunate fourth and eighth graders were chosen, but not from this school I don’t think. Actually I don’t know. But anyway, there was a social studies test, a math test, a reading test, and a science test.  Somehow I got to take the science test and miss physics…But anyway, it included biology and chemistry and physics. The physics part mostly consisted of graph interpretation which we practiced so much during the first quarter so I had no problem of course. It also asked us questions about our science class like how often do you watch videos and how often do you talk about current events in your science class? I pretty much put always for everything because that sounded good to me. Haha.

New York had a lot of static electricity. Yeah. Especially in our hotel room at the Sheraton Manhattan. And also probably because of the really fluffy with jacket i was always wearing to keep warm. Every time i would go to answer the door and touched the doorknob, i would get shocked. You would think that I would have figured out how to get rid of the static electricity sooner rather than never, but yeah, no. Not really. And I could hear the static everytime I took off my jacket. And went around chasing my roommates around the room. In physics we learned that I probably could have just touched the wooden door and avoided all of that trouble. That would have been very helpful to know. But since Hawaii doesn’t have a large static electricity problem, I had no idea. We don’t have  a huge problem here because of all the water surrounding us. Drier climates have a much larger chance of being electric. Like Las Vegas.

This is a picture in our hotel, just outside the elevators. I am probably not static-y at this point because I touched the doorknob to leave the room.
