Static vs Dynamic
What is the difference between static electricity and dynamic electricity?
Static is a stationary charge while dynamic is a moving charge.
Example: static cling vs live wire
What is Coulomb's Constant's value and units?
~9 x 10^9 N*m^2 / C^2
Calculate the electric potential energy of two electrons 8 picometers away from one another.
2.88 x 10^-17 J
(Aubrey)
What is the charge of an electron?
-1.6 x 10^(-19) Coulombs
List all the colors in the rainbow in alphabetical order
Blue, Green, Indigo, Orange, Red, Violet, Yellow
DAILY DOUBLE
Which of the following is not an example of static electricity?
1. A cat covered in foam packing peanuts
2. A battery powering a lightbulb
3. A sock clinging to a fabric shirt
4. A balloon attracting hair off a person's head
5. A child sliding down a playground slide
What is Coulomb's constant equal to in terms of Electric Field strength, distance, and charge of a particle?
(E*d^2)/q
The electric potential energy of two charged particles is 2.8 x 10^-4 J. The particles are separated by 4 picometers and the first particle has a charge of 3.6 microcoulombs. Find the charge of the second particle.
3.46 x 10^-20 C
(Grayson)
Explain the electron transfer between a person's head and a balloon they rub against themselves
The electrons from the hair are transferred to the balloon through friction, thus making the balloon negatively charged and the hair positively charged.
In the minecraft video game, what is the smallest hostile mob?
Endermites
What are the three most common ways electrons can influence an object(s) to become charged?
Friction, Conduction, Induction
What are the units of Electric Field strength?
Newtons per Coulomb
Calculate the electric potential of a proton placed 5 picometers away from a point.
-2.88 x 10^2 V
(Kei)
Why is electron transfer the main focus rather than proton transfer even though they have the same charge?
Electrons are much smaller so they are alot easier to move around and influence objects
What year did women earn the right to vote in America?
1919-1920
Provide and explain a scenario of a person using at least 2 of the 3 methods to charge or influence a charge of an object?
example: balloon rubs on head (friction), balloon sticks on wall (Conduction), balloon is brought near neutral object (induction)
What are the units of Electric potential? What is an alternative way of labeling the same unit?
Volts or Joules per coulomb
Calculate the electric potential energy of two particles with -3 picocoulombs and +2 micro coulombs. The two particles are placed 4 micrometers apart from one another.
-13.5 x 10^-4 Joules
(Ellie)
Jon rubs a balloon against him own head so that he can see his hair begin to attract to it. He then brings the same balloon near his friend Ethan. Ethan's hair begins to repel away from the balloon almost splitting. explain why
Jon gave the balloon a negative charge and when brought near Ethan's hair it repelled away. Ethan's hair must have been slightly negative as well.
The Tripods novel is a trilogy, what are the names of each book?
White Mountains
City of Gold and Lead
Pool of Fire
Explain how a battery showcases both static and dynamic electricity
Static when the battery is disconnected and dynamic when the battery has a current flowing (plugged in)
DAILY DOUBLE
What is coulomb's law?
2 protons and 2 electrons are set in a straight line in an alternating pattern (proton, electron, proton, electron). The distance between each particle is 8 millimeters. What is the electric potential at the halfway point of the entire system?
0 Volts
(Jayden)
A standard battery will always have an anode and a cathode, which side is positive and which side is negative? Which way do the electrons flow in a battery when connected?
Anode is negative and Cathode is positive. The electrons from the anode flow towards the cathode side.
Since its debut in 2007, how many different iphone models have there been?
46 different iterations
