Learn About Forces: Terminal Velocity and More!

A comprehensive guide to fundamental physics concepts focusing on forces, motion, and their relationships. This guide explores the relationship between force and acceleration, types of forces, and key physics calculations.

Forces are classified into contact forces (requiring physical touch) and non-contact forces (acting at a distance)
Understanding balanced and unbalanced forces is crucial for predicting object motion
The guide covers essential concepts like terminal velocity, spring forces, and pressure
Mathematical relationships and units are provided for key physics quantities
Vector quantities like velocity and force are explained with their directional properties

Force Relationships and Terminal Velocity

This page explores the concepts of balanced and unbalanced forces, introducing calculating terminal velocity physics principles.

Definition: Terminal velocity occurs when the upward forces $drag and buoyancy$ equal the downward force of gravity, resulting in constant velocity.

Highlight: Force equals mass times acceleration $F = ma$ , and weight equals mass times gravity $W = mg$ .

Example: For objects on Earth, the gravitational field strength is 10N/kg, which helps calculate weight from mass.

Vocabulary: Balanced forces have equal magnitude in opposite directions, while unbalanced forces result in acceleration.

Physics Measurements and Units

This page details the essential measurements and units used in physics calculations, particularly focusing on force-related quantities.

Definition: Pressure is defined as force divided by area, while moments are calculated as force times perpendicular distance.

Highlight: An object achieves rotational equilibrium when clockwise and anti-clockwise moments are equal.

Example: Levers demonstrate the practical application of moments, where force times distance from pivot determines the turning effect.

Vocabulary: Key units include:

Speed: metres per second $m/s$
Force: newton $N$
Pressure: newtons per metre squared $N/m²$
Acceleration: metres per second squared $m/s²$

I love this app so much, I also use it daily. I recommend Knowunity to everyone!!! I went from a D to an A with it :D

Philip, iOS User

The app is very simple and well designed. So far I have always found everything I was looking for :D

Lena, iOS user

I love this app ❤️ I actually use it every time I study.

Forces and Motion Fundamentals

This page introduces the fundamental concepts of forces in physics. Forces are divided into two main categories and their relationship with motion is explored through basic calculations.

Definition: Forces are vector quantities that have both magnitude and direction, capable of changing an object's motion or shape.

Vocabulary: Contact forces require physical touching between objects $friction, reaction force$ , while non-contact forces act at a distance $gravity, magnetic force$ .

Example: Speed calculation demonstrated through distance-time relationship: Speed = distance/time For instance, 10/5 = 1.5 m/s

Highlight: Understanding vectors is crucial as forces have both direction and magnitude, making them different from scalar quantities.

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.

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.

Best app on earth! no words because it’s too good

Thomas R

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

David K

iOS user

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.

Greenlight Bonnie

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

Rohan U

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

Elisha

iOS user

This apps acc the goat. I find revision so boring but this app makes it so easy to organize it all and then you can ask the freeeee ai to test yourself so good and you can easily upload your own stuff. highly recommend as someone taking mocks now
