Hope you all are cat lovers. I've always been more of a dog person, but there was no video called "Dun Dysics with Dogs." Watch the video (at right) and share something you learned from it? Be detailed and accurate in your response...."I learned about friction" isn't the kind of response we're striving for. You all did a fantastic job with your responses on the last blog post -- keep up the great work!
:) Mr. R
I learned there are 2 different types of charges: negative and positive. Alike charges repel and opposite charges attract. And also, conductors allow charges to flow through easily and insulators prevent charges from flowing easily.
ReplyDeleteAs Mr. Roman always says, a lot of the physics we are learning this year we already know intuitively. Such was the case with many of Purrfesor Meow Mentum's lessons (like attracting opposites).
ReplyDeleteCats are conductors because they easily conduct electricity but rubber is NOT - it is an "insulator." (Fun fact - the nonstick Teflon, another insulator, is used as a nickname for politicians to whom scandals don't "stick." ie, Ronald Reagan)
I also learned mu is the coefficient of friction and that an object's netchange is 0 when negative and positive charges are equal.

In this "Phun Physics with Phelines" episode, I learned about Electrostatics. There are positive and negative charges; opposite charges attract each other and alike charges repel each other. I also learned that the arrangement of protons and electrons within the atoms of an object determines whether the object is a conductor of electric charges or an insulator, like rubber. Also, most objects have a net charge of zero because they have an equal amount of positive and negative charges. When some items are rubbed together, electric charges are transferred. As a side note, I found the cat falling off the roof joke funny, and I learned that mu is the coefficient of friction.
ReplyDeleteI learned that there are 2 types of charges (positive and negative), from Purrfesor Meow Mentum, the talking cat. This reminded me of Newton's 3rd law-every action has an equal and opposite reaction. We did an example in class today where Sibella and Camilla tried to push each other while sitting on the rolling platforms; they each ended up repelling each other backwards, which reminded me of 2 alike charges repelling (+, +; -, -). I also learned that like sometimes in life, opposites attract (as in opposite charges of +,- in this case). Also, I found out that cats are conductors (can conduct electricity), while rubber is an insulator (canNOT conduct electricity). Finally, I learned that mu is the coefficient of friction and that the net charge of an object is 0 when there's an equal number of positive and negative charges.
ReplyDeleteI learned that mu is a coefficient of friction, but I didn't learn much more about that from the video. I learned that static electricity is a result from the exchange of electrons when two objects graze each other. I also learned the fact the amount of cat hair attracted to dark clothing is related to its darkness. I also learned that physics is phun...............
ReplyDeleteIn the video, I learned that two opposite charges will attract and thus two of the same charges will repell against each other. If something has an equal balance of both negative and possitive charge, then its net charge will remain 0. Also, I learned that insulators block potential charges, whereas conductors encourage charges to transfer. xx
ReplyDeleteI learned that friction , or the rubbing together of two materials transfers certain charges onto one one other and give ach a net charge.
ReplyDeleteFrom Phun Physics with Phelines, I learned from Professor Meow Mentum that the ease at which electricity is able to flow through an object is based on the formation of the object's atoms' protons and electrons. If electricity cannot flow through an object, that object is called an insulator. Also, when two objects with net charges of 0 are rubbed against each other, some electrons are transferred, giving each object a positive or negative net charge.
ReplyDeleteIn the video, I learned about electrostatics. There are two types of charges positive and negative. The opposite charges attract each other and the same charges repel. For example ++ repel and +-attract. I also learned about protons and electrons. Most objects have a net charge of zero because there are equal + and - charges. However, you can transfer atoms to affect the charge of something.

I learned that cats are conductors allowing electricity to travel through their body, while rubber in contrast is an insulator, and does not allow electricity to travel through it. Each object contains a charge, specifically a negative and positive charge. In most objects the charges are equal making the net charge of the specific object 0.
ReplyDeleteIn the youtube video I learned about positive and negative charges of electrostatics. I learned that opposite charges attract and alike charges repel. I also learned that some objects conduct electricity more easily such as cat, whereas, rubber duckies, made out of rubber, do not and are called insulators. Net charges are created when two objects rub together and can equal zero when the positive and negative charges are balanced. On the other hand, net charges can be negative or positive when one object receives an unbalanced amount of negative to positive electricity.
ReplyDelete1. When two or more objects rub together, they can exchange protons and electrons.
ReplyDelete2. Opposite charges attract and same charges repel.
3. Rubbing objects together with different charges can cause friction (for example, sliding on carpet in socks).
In the video, I learned that there are positive and negative charges of electrostatics. In electrostatics, I learned that opposite charges are attracted to one another, while alike charges repel. I also learned that rubber is not a good conductor of electricity, also known as an insulator.
ReplyDeleteI learned that there are two types of charges, both positive and negative. Opposite charges attract each other and same charges repel one another. I also learned that the arrangement of the atom in the charge deals directly with its ability to conduct or insulate electricity.
ReplyDeleteI learned that for every negative charge there's a positive charge. Cats produce electricity because of their fur and net charges can be positive or negative if one side is unbalanced.
ReplyDeleteI do not like cats, at all, but i actually learned a lot from the video. I learned that there are positive and negative charges. An object's "net force" depends on the object's proton or electron count. When two opposites attract and are rubbed together, one object transfers charges to the other, changing the net force from 0 to either positive or negative. Insulators repel conductivity while conductors transfer charges quickly. I also didn't know that fur was a conductor.
ReplyDeleteIn the cat video I learned that similar charges (such as positive and positive) will repel each other, while opposites will attract. I also learned that a cat's arrangement of protons and electrons allow it to conduct electricity easily, making it a conductor. On the other hand, rubber does not conduct electricity so it is an insulator. I also discovered that two materials can transfer atoms when rubbed against each other, giving one material a negative net charge.
ReplyDeleteAlso, cats make great physics teachers.
I learned that protons and electrons can be transferred from one object to another. Also opposites attract while two ions with the same charge repel each other. I also learned that objects that are not good conductors are called insulators.
ReplyDeleteFrom the Phun Physics with Phelines video I learned that opposite charges are attracted to each other. Also that the electrons can be passed from an object with charge to another through a certain process. + and + charge rejects each other as well as - and -. A net charge is the equivalent amount of charges positive and negative in an object.
ReplyDeleteFrom the video Phun Physics with Phelines I learned that each object contains charge; an object contains an equal number of negative and positive electrons which gives a net charge of 0. I learned that the net charge is changed from 0 when two objects rub against each other and share their electrons; one becomes a net negative charge and the other becomes and net positive.
ReplyDeleteThe Phun Physics with Phelines lesson taught me that an equal number of negative and positive charges in a n object gives it a net charge of 0. Paula Abdul taught me that opposite charges attract.I think the most important lesson I learned from this informative video was that cats have thee ability to speak.
ReplyDeleteI learned from the video that all objects have a balanced set of both negative and positive charges giving them a net charge of zero! I also learned that rubbing two balanced objects against each other transfers electrons from one of the objects to the other cause one to become positive and the other to become negative. This is why we can get shocked by static!
ReplyDeleteI have learned that negative charges and positive charges are "attracted" to one another, while having the same charges going against each other creates a repellent between the two same charges. Also, I learned that mu means the coefficient of friction.
ReplyDeleteI learned that mu is the Coefficient of friction. I also learned that opposite charges attract, and that the particular arrangement of a material's atoms determines the resistance to electricity. Rubbing objects together can affect net charge. I also learned that Paula Abdul used to be a singer.
ReplyDeleteI learned that negative and positive charges attract to one another and also that same charges repel from on another.
ReplyDeleteI learned that there are two types of charges, negative and positive charges. Alike charges will repel each other while opposite charges will attract. Some objects are conductors of these charges, which means that it allows the charges to pass through them easily, such as the body of a cat, while some objects are insulators, which means that it does not let the charge pass through it easily, such as a rubber duck.
ReplyDeleteIn the video, I learned that a cat's body allows electric charge to travel easily through it,thus explaining as to why it is a conductor. Rubber has atoms arranged such that it is more difficult for electric charges to follow through, making it an insulator. I also learned from the joke of the day, that mu is the coefficient of friction.
ReplyDeleteThe hilarious yet knowledgable cat taught me that there is two charges in the universe positive and negative. According to this cat when you put to positives or two negatives together they repel. However, when opposites such as positive and negative charges come together they attract. Finally, i learned the differnece between a conductor and an insulator. a conductor means that charges will easily pass through objects, whereas insulators it is harder
ReplyDeleteIn this video I learned that Rubber is an insulator and metal is considered a conductor. Another thing I learned is that opposite charges attract from one another where as two same charges repel.
ReplyDeleteIn the video I learned that there are 2 types of charges: negative and positive. The way atoms are arranged determine whether an object is a conductor, where electricity is easily passed through or an insulator where electricity is not easily passed through. I also learned that an objects negative charge can rub off on another object, which relates to net charges.
ReplyDeleteI learned that an object's arrangement of atoms determines whether an object isa conductor of electricity or an insulator. And that each object has a net object of 0 however when two objects rub together they give eachother different charges.
ReplyDeleteIn "Phun Physics for Phelines" I learned about negative and positive charges, and conductors. Two opposite charges (+ and -) will attract while two similarly charged atoms (+ and +) will repel. A conductor is an object which can transfer an electrical charge easily in comparison to an object such as rubber.
ReplyDeleteIn this marvelous cat video "Phun Physics for Phelines" I learned that the two types of charges are negative and positive, the same charges repel each other while opposite charges attract. Electrons and Protons can be passed through one object to another. When a charge does not pass through a good conducting object it is not called a conductor but an isolator. An object is called a conductor when a charge passes through an object easily.
ReplyDeleteI learned that the relationship between positive and negative charges is called electrostatics
ReplyDeleteI learned that when you rub a rubber duck on a cat, his fur will stand up BECAUSE of the electrons moving form the fur to the duck. Similarly, I learned that something is either a conductor or inductor, depending on how its atoms are arranged.
