How Forces Change Speed: Balanced vs. Unbalanced

Forces and Motion in Physics: Understanding how forces affect object behavior and movement through fundamental physics principles.

  • How balanced and unbalanced forces affect velocity is demonstrated through everyday examples like hanging fruit and moving balls
  • The relationship between mass, force, and acceleration is explained through the fundamental equation F = ma
  • Multiple examples of action and reaction force pairs are provided, including person-box and boat-water interactions
  • Key physics concepts include velocity, force, mass, and acceleration, with clear distinctions between vector and scalar quantities
  • Real-world applications help illustrate the differences between balanced and unbalanced forces

I love this app so much [...] I recommend Knowunity to everyone!!! I went from a C to an A with it :D

Stefan S, iOS User

The application is very simple and well designed. So far I have found what I was looking for :D

SuSSan, iOS User

Love this App ❤️, I use it basically all the time whenever I'm studying

Forces and Motion Fundamentals

This comprehensive page explores the fundamental concepts of forces and their effects on motion in physics. The content begins by establishing that forces are essential for changing an object's velocity and explains how the direction and strength of forces influence motion.

Definition: Force is defined as a push or pull upon an object that can alter its state of motion or shape.

Highlight: The relationship between force FF, mass MM, and acceleration AA is expressed through the equation F = ma, which can be rearranged to find any variable when the other two are known.

Example: When a person pushes a box, there are two equal but opposite forces at work - the person pushes the box forward while the box pushes back on the person with equal force.

Vocabulary:

  • Velocity: Speed in a particular direction
  • Net force: The sum of all forces acting on an object
  • Vector quantity: A measurement with both magnitude and direction
  • Scalar quantity: A measurement with only magnitude

Highlight: Balanced forces occur when equal forces act in opposite directions, resulting in no movement, while unbalanced forces lead to motion due to one force being stronger than the opposing force.

Example: An apple hanging from a tree demonstrates balanced forces - gravity pulls down while the branch provides an equal upward force. Conversely, kicking a soccer ball shows unbalanced forces, where the kicking force exceeds the ball's resistance.

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.

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.😋🩷🎀

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 😍😁😲🤑💗✨🎀😮

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!
