No Wires World

Physics homework for 2/24/15:

New Light

        Today we learned about circuits and we did a little lab involving steel wool, a light bulb, and a generator.

         Imagine a world where no wires are needed to help electricity flow - for a logical reason or not - and where technology would still work without the wires letting the electricity flow. This world sounds like quite an efficient one as less material for wires is needed and as we could help generate electricity faster because we do not need to focus on the wire part of it all. I would name this world "Wireless Connection" (HAHAHAHA--*SHOT*). The reason why is because electricity can sort of "connect" and interact plus help technology function without any wires. 

        One cool thing you could do with electricity that can function without wires is you can possibly harness tons of energy on your own and discharge it into whatever you need to power up. And it would power up which sounds cool! It's like you'd have super powers~. Or maybe you wouldn't need to manually turn on things to make items work. You could also maybe float if you're oppositely charged to a certain part of the ground? Maybe you could also just light a light bulb up by simply moving around as the electrons from me and the surrounding area would just go to various items like the light bulb, making them work. 

        One bad thing that could occur is people could get lightning shot at them or explosions could occur and/or fires. The reason why is because the wind could blow ions into your hair or something, charging it and thus making it static, and too much build up could cause sparks or it could cause huge fires/explosions. Lightning also will strike you if your hair is positively charged as it will be attracted to your hair and as it will want to find something to discharge into (it may go to a metal, but not always). Plus, too much build up in general can cause overheating and then a fire and it'd be much easier for that to happen a lot. A crazy thing that could happen is various light shows and sparks since the electricity can easily hit more metal and can easily light a lot up more at a variety of times. All of those charges would flow to certain objects and create sparks because of the discharge/current or the objects would light up because they'd be receiving electricity that can convert into heat and light energy whilst also powering something up.

Good night! :DD

Electricity So Far

Physics homework for 2/12/15:

Current Progress

         Electricity is a form of energy that results from the existence of charged particles and/or resulting from a current. So far I learned electricity can come from various places, but always needs some kind of a turbine/generator for it to be used right. Different types of currents like alternate and direct currents can flow to power items like light bulbs so long as there is a generator, for example. I have also learned that you need charged particles for current and that there are various ways to charge atoms (induction, friction, etc.) Additionally, electrons are important in generating electricity currents as they provide the negative charge, heat, and energy to power items up. Plus, the materials that are used to conduct electricity like metal or rubber are important and essentially you want to utilize conductors for electricity purposes. Electricity is important because of how major and significant of a power source it is. It powers the very laptop I use to complete my homework on, it generates energy for my lights, it takes care of the city's power, etc. Humans are VERY reliant on it too, and with out it we would all definitely have some trouble! I'm still confused about mainly how to charge objects, but I am fair at that. I have grasped the concept much more, but I think there might be a few things confusing me. If I remember, I will probably add it here but for now I think it's just charging. And as for today's lab, I guess only the types of currents were confusing but only because I heard the concepts once. I'm getting better at how electrons work and about charging too even though it may still confuse me a bit. Also getting better at understanding how particles work. I have a question about electricity, is it a renewable resource? Is it easy to obtain and generate? And how do batteries work to help with electricity? 

:333 <3 Happy early Valentine's Day!! Have a good night! :D

Electricity Vocabulary

Physics homework for 2/11/15:

Check Your Progress: Electricity

       Today in class we mainly worked in groups on vocabulary and we did various vocabulary related activities like a little test and a discussion.

          Even before taking physics people know a general bit about electricity, but here is what I know about electricity so far as a result of physics class. Electricity is a form of energy that results from the existence of charged particles like protons and electrons as neutrons cannot be charged. Plus, as protons are the positive part in the middle of an atom and as electrons are the negative part moving freely around the atom the charges are either positive or negative and atoms are only charged when either the protons or electrons are greater than each other. Depending on which one is greater than the other, the atom will either be positively charged or negatively charged. Now, as electrons are the only part of atoms that can move easily they tend to either flow freely through items when moved or they tend to stick to things. Conductors like metal allow electrons to flow through them, but insulators like glass won't allow the electrons the flow through. In fact, the electrons will just sit on the glass looking all pretty and stuff! And if someone were to swipe all the electrons up into their hands and then say touch a door knob or something that conducts electrons well, then the electrons would quickly discharge as a current through the conductor because they have an opportunity to. This discharge is known as "static electricity". Finally, as we all know, opposite charges will attract (negative and positive). But similar forces will repel (negative and negative/positive and positive).

       This was a very broad paragraph about electricity as there is more to it, but generally this is what I know :)!!~

      

D: OH NO!! :( 

Have a good evening friends vwv7!!!~~ :333

Van de Graff

Physics homework for 2/5/15:

Huge Metal Balls (Van de Graff)

            Today we talked about electrostatic charges as well as took some notes and did a few interactive things and group work. We also got to see a Van de Graff in action!

The Van de Graff did a variety of different things, but I'm assuming only a handful of things need to be described and what not. 

         One thing the Van de Graff did was was it ended up shocking one of the balls on a stick when the ball got close to the generator. The reason this happened was because the belt inside the machine was made of rubber (which is an insulator) so it ended up picking up electrons from the big metal ball on top of the machine and from the air inside of the machine maybe? These electrons probably made the belt negatively charged and as the big ball was made of metal it was a good conductor. So, the electrons from the belt ran through the big ball and straight through to the other ball because it was ALSO metal! The charge must have been strong enough and the balls were in close distance with each other. Whenever the electrons moved through the balls a little blue spark was seen because the electrons were being conducted through the metal. (Also, Miss Reid did not get shocked because she was holding a wood stick that was holding the ball so the wood protected her because of its insulating properties). Plus, I believe since the ball was neutral the electrons from the big ball interacted with the protons from the little ball causing static electricity.

       Another thing the Van de Graff did was it lit up a little glow stick attached to a wooden stick when the glow stick touched the big metal ball. The explanation for this is basically, once again, the electrons from the belt flow to the metal ball all the way through to the little glow stick. And as the electrons obviously have some energy, spark, and what not they give the glow stick some energy to light up but not so well because the electrons flow out through one end of the glow stick instantly afterwards. 

      Additionally, the little ball was also repelled at one point from the big ball. Reason being is the big ball was already negatively charged, and once the little ball was also negatively charged (by rubbing it against the big ball which caused some electrons to be taken away and attracted to some protons) the balls wanted to repel from each other whenever they got close. Why? Because similarly charged objects naturally repel! And since both balls were negatively charged they both wanted to get the hell away from each other!

    Finally, to sum the last two parts up quickly we also had a little silver ribbon that flew towards the big metal ball and flew away from it after and repeated this cycle for a while as well as Miss Reid getting her hair done :3 (poor Miss). The ribbon was in its little cycle due to the fact that at first it was positive so it was attracted to the negatively charged big ball (because opposites attract). BUT, once it actually touched the big awesome ball it stole some electrons causing it to be negatively charged which made it repel from the negatively charged ball. Even then once the ribbon flew back and away from the big magical ball it gave away electrons so then it was positively charged which caused it to go BACK to the negatively charged ball! Ugh, so biPOLAR--hUEUEUEUEHHEHEHEHAHAHAHA--*SHOT* And Miss Reid touched the big metal ball which caused her hair to float majestically. Why? Because why the *bleep* not? It's for physics :33--oh you mean why did her hair float? Well, that's because the electrons from the metal ball flowed through her hand and spread up to her hair which probably negatively charged it a lot and since a lot of her hair was negatively charged the hair must have repelled from itself. 

Extra: Hmm, what would I wanna do with a Van de Graff? I would be that one weirdo who grabs a Barbie and tries to make its hair stand up. >:-)))) mUAhAHA--No, but really, maybe I'd try to make something like paper float up by holding my hand above it while touching the Van de Graff? I've heard of people doing stuff with paper and fabric. Basically I think since I'd be negatively charged the paper would be attracted to me and stuff but that sounds boring. Levitation is cool though! Maybe we could make stuff levitate like little paper airplanes?? :DD I'm not quite sure how it'd all work but I believe you'd need many things with the same charge so that everything could just repel and float up. Maybe the little balls are needed for this too? Dunno, but there are just weird ideas :333.

Insulators & Conductors

Physics homework for 2/4/15:

Day Full of Insulators and Conductors

         Today we came back from the barren snow days of the weekend and we focused on atoms as well as on insulators and on conductors. 

So one conductor I came in contact with today was metal (mostly iron) from chairs and as well as from other things like knives as well as door knobs and what have you. For example, I had to make myself a delicious sandwich this morning and I needed to spread the cream cheese onto it so I grabbed a knife to help with that. After spreading the cheese and all that mumbo jumbo I had to wash the knife off and I noticed a few things about the knife. One, it was pretty light looking and what not but it actually feels pretty dense and fairly cold once you touch it. Especially after running it through some cold water. I knew the knife's metal was a conductor because conductors allow electrons to move, meaning the knife would take my electrons and would let them flow through the knife easily which I felt. I instantly felt cold on contact with the metal meaning the metal must have let my heat/electrons flow through it. Plus, I know that metals are conductors but that doesn't cover all the electrons and stuff.

As for an insulator, today I obviously came in contact with air and what not, but I also came in contact with things like plastic and wood from my writing utensils as well as certain fabrics from my clothing. But wood will be used as the main example. When writing with my pencils they usually always feel light and not so dense, plus not cold or hot unless say I've been holding it tightly in my hand for hours or say unless they've been outside in a cold environment for quite some time. So it usually feels like a moderate temperature whenever I hold a pencil. Pencils are definitely insulators as insulators don't allow electrons to flow through and that's exactly what it felt like. Whenever I touched a pencil I was never given heat and I usually never gave heat or any electrons, I just remained the same similar temperature. Of course some transfer must have occurred, but it must have been significantly small.

Now, both items are different as one item allows electrons to flow freely through and the other doesn't allow them to flow freely through. They also are composed of different materials with different densities. Additionally, when felt both items do not feel the same temperature-wise as one item takes more heat and as the other item just does barely anything. Also, if you were to conduct electricity through these materials then the metal would make a great conductor for the electricity while the wood wouldn't allow the electrons to go through the wood and what not. These are the main differences, I believe. 

Aww :33 <3

I kinda get this one xD <3.

Yes >:3.

Bow to it >:DDD!! MUAHAHAHA--

:33 Have le good day people of Earth, I loves yeayeayea <3.
