3.1 fungus theory for 31$ cash or card Flashcards
If you rub two items together like a balloon and a fabric the ballon becomes_____
Charged
T/F 2 items are charged through friction, only one item is charged. This is called static electritcity
F: Both items are charged one N and one P
T/F
No matter what, (The electrons) are always immoble in the atom
The nucleous (noyau)
La deplacement des electrons AKA ______ et c’est ce qui rend un objet son ____
le transfert d’electrons | charge
What signifies “statique”?
stationnaire ou immobile.
la Loi de l’attraction et de la répulsion indique que ___.
Des charges identiques se repoussent et des charges différentes s’attirent.
Quels miniscules particules est toute substance composée de?
des atomes
Comme les ____ sont en même nombre que les ____ alors on dit que l’atome est neutre.
Comme les charges positives sont en même nombre que les charges négatives, alors on dit que l’atome est neutre.
Qu’est qui qui rend un matériel chargé?
le déplacement des électrons (le transfert d’électrons)
Si un électron est enlevé d’un atome neutre, l’atome sera chargé ______ ce qui entraine que le matériel sera chargé ______
positif, positif
T/F Normally in static electricity, you need an equal amount of positive and negative charges but there are exceptions
F: There needs to be a equal amount at all times
La charge d’un materiel est dependent de les charges des ____
atomes
T/F You can produce static electricity from rubbing to already charged items together
F: It’s only produced initially from neutral items
Neutral objects have what kind of charges
positif et negatif
La Loi de ___ et de ___
la Loi de l’attraction et de la répulsion.
Les ____ enlevés d’une partie d’un isolant ne sont pas remplacés par d’autres électrons.
electrons
T/F, replace bold words:
Negative charges will be more spread out in conducters because they inhibit electron movement.
They will be more spread out because they allow electrons to move freely.
Dans un fil électrique où est l’isolant et où est le conducteur ?
the plastic part outside is the isolant, the copper wire inside or whatever is conducteur
if you rub two identical neutral objects together, will they become charged?
no, because they are the same so they have the same capacity to gain or lose charge, so they stay neutral
T/F: neutral objects are NOT attracted by charged objects
F: neutral objects are attracted with charged objects
How are neutral objects attracted by charged objects?
Eg: if the charged object is positive, it will push away the positive charges inside the neutral object, leaving negative charges in the area of the neutral object close to the charged object, and positive and negative attract.
Briefly explain what isolants are.
They are substances or objects that strongly retain their electrons
Examples of isolants include,
glass, cermamics, dry wood, and plastic are all great examples of isolantes
Brielfy explain what conductors are
Conductors are substances of objects that “prefer” the movement of electrons between objects
T/F Even though conductors prefer the movement of electrons this doesn’t mean that it’s electrons can move freely.
F: Electrons can move freely in conductors. They are called in french, electrons libres.
Metals are considered very good conductors because that they always have at least 1 _____that they can _____
electron | transfer
il y a __ lois des charges electrostatiques, ils disent que ____
charge memes se repoussent, charges opposees attirent, charge neutre attire charge positif ou negatif
quand un objet est charge electriquement a un certain distance, ca s’appelle
charge par induction
un objet est charge en le touchant avec un objet charge. ca s’appelle
charge par conduction
la force electrique est un ____
force a distance
quel est l’unite pour la charge electrique?
coulomb (C), chaque coulomb represente environ 6,25 x 10^18 electrons
Sending electricity directly into the ground is ______
mise a la terre
