Quarter 3, Blogpost #3

I'm sure this same picture is going to be used a lot, but i really liked how Mr. Blake used a battery demo to teach us the difference between electric potential and electric potential energy. At first, this concept was a little confusing because both contain the same name, but are not actually the same at all. Electric potential energy is measured in joules just like any other form of energy. To calculate electric potential energy, the same equation for finding potential energy is used: work = average force x distance. This is electric potential energy. Electric potential is something entirely different. Electric potential is measured in volts or joules per quantity of charge. In order to find electric potential, the following equation is used:

electric potential = work in joules/unit of charge moved in coulombs

Electric potential is also known as "voltage". So by the looks of the two definitions, electric potential energy is used to find electric potential. In class, Mr. Blake used a battery demo to explain voltage to the class. He said that although the voltage of an object is high, the shock we feel is dependent on how charged the object is. For example, if an object has a voltage of 100,000 volts, the shock is dependent on whether or not the object has a high or low charge.

Quarter 3, Blogpost #2

Sooooo this blogpost was supposed to have been done last weekend, but once again, I forgot to do it. Not a very good way to start off the second semester, already forgetting to do my blogposts haha. But anyway, here it is. Last friday I slept over my friend Brandiʻs house in Kaneohe. I live in Kapolei where itʻs never cold, so experiencing Kaneohe weather was a lot different. For dinner we picked up food from Jack-in-a-box and took it to the pier that Brandi always goes to. It was really nice to sit and eat near the water, but it was freezing ! Right when we got back to her house I ran to grab my fuzzy socks. Arenʻt they pretty ?(: While I had them on, for some odd reason I wanted to see if I could shock Brandi while she was laying down. But it didnʻt work. So in disappointment, I dragged by feet across the rug to her room and touched the door knob. Thatʻs when I got shocked. What happened was both me and the door knob contained a neutral charge. But, when I rubbed by feet across the rug, they became either positively or negatively charged. So when I touched the door knob, our different charges wanted to even out, creating an electric shock. I really hope I explained this right. I better have being that Mr. Blake used this example a million times lol.

Quarter 3, Blogpost #1

1st blog post of 3rd quarter..........yaaay (: haha. So as our first blog post, we will be discussing Electric Charges, Forces, and Fields. There are three different types of atoms that posses three different charges: protons, neutrons, and electrons. Protons are positively charged atoms. Neutrons are atoms that posses no charge or are neutral. Lastly, electrons are negatively charged atoms. Objects that contain these atoms often experience attraction or repulsion toward other objects that are not caused by gravity, springs, or other contact forces. This week, we've learned about which charges attract each other and which charges repel. Like or similar charges repel each other such as two positive charges, two negative charges, or two neutral charges. Different or unlike charges attract. Such as a negative charge and a positive charge or a negative charge and a neutral charge. The picture above shows some of the magnets we have outside on our washing machine (&yes, I do mean washing machine, but thats only because we have stainless steal refrigerator and the magnets won't stick to it lol). But anyway, I think its safe to say that the magnets and the washing machine both hold a different charge, displayed by their attraction to each other. If the magnets and the washing machine had similar charges, the magnets would not stick.
