Page 2: Field Density and Electric Field Strength

This section explores how field line density relates to field strength and introduces the concept of electric field strength measurement.

Definition: Electric field strength is the force per unit charge on a positive test charge at a point in the field.

Highlight: Field line density directly indicates field strength - closer lines mean stronger fields.

Example: Two point charges create radial field patterns similar to magnets, while distant point charges produce more uniform, linear patterns.

Vocabulary: Newton per coulomb NC1NC⁻¹ - the unit of electric field strength.

Page 3: Test Charges and Work Done

This page details calculations involving test charges and work done in electric fields between parallel plates.

Definition: Work done on a test charge between plates is calculated as W = Fd.

Highlight: Electric field strength can be calculated using potential difference and plate separation.

Example: In parallel charged plates, field lines are uniform, parallel, and perpendicular to the plates.

Page 4: Charge Distribution and Permittivity

This section covers how charges distribute on conductors and introduces the concept of permittivity.

Definition: Permittivity of free space ε0ε₀ is a fundamental constant in electrostatics.

Highlight: Charges distribute themselves equally over conductor surfaces, with irregular shapes leading to charge concentrations.

Example: Greater charge concentrations result in increased electric field strength, shown by denser field lines.

Page 5: Electric Potential and Equipotentials

This page explains electric potential and equipotential surfaces in electric fields.

Definition: Electric potential is the work done per unit charge to move a positive test charge from infinity to a position in an electric field.

Highlight: Work done between equipotentials equals the potential difference multiplied by charge.

Example: Closer equipotential lines indicate greater potential gradients.

Page 6: Point Charges and Field Relationships

This section explores relationships between electric field strength, potential, and distance for point charges.

Definition: Electric field strength is the negative gradient of the electric potential-distance graph.

Highlight: The area under the electric field strength-distance graph equals the change in potential.

Page 7: Force Interactions Between Charges

The final page covers force interactions between multiple point charges.

Definition: Net force between multiple charges can be calculated using vector addition.

Example: For two positive forces acting at an angle, the resultant force is calculated using F = √F1F₁² + F2F₂².

Highlight: Forces between like charges are repulsive, while forces between unlike charges are attractive.

Page 1: Electric Conductors and Field Patterns

This page introduces fundamental concepts of electrical conductivity and field patterns. Electric conductors, primarily metals, contain free electrons while insulators have electrons bound to atoms.

Definition: Field lines are paths that positive test charges follow in an electric field.

Highlight: Unlike gravitational forces which are only attractive, electric forces can be both attractive and repulsive.

Example: A uniform electric field pattern shows parallel field lines between oppositely charged plates.

Vocabulary: Test charge - a negligibly small positive charge used to map electric fields without disturbing them.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha Klich

Android user

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Anna

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
