Easy Guide to Physics Formulas and Newton's Laws

Physics helps us understand how objects move and interact in the world around us through mathematical formulas and scientific principles.

Introduction to Physics formulas and concepts forms the foundation for analyzing motion, forces, and energy. Students learn essential equations like F=ma (Force equals mass times acceleration) and how to apply them to real-world scenarios. These fundamental concepts help explain everything from why a ball falls to Earth to how rockets launch into space.

Applications of Newton's laws in physics problems demonstrate how forces influence motion in our daily lives. When you push a shopping cart, throw a ball, or ride a bicycle, Newton's laws describe the forces at work. The first law explains why objects stay still or keep moving unless acted upon by a force. The second law shows how force relates to acceleration, while the third law reveals that forces always come in pairs - for every action, there's an equal and opposite reaction. Understanding rotational motion and angular momentum builds on these principles by explaining how objects spin and rotate. This includes concepts like torque, which measures the turning effect of a force, and conservation of angular momentum, which explains why figure skaters spin faster when they pull their arms close to their body. These rotational concepts help us understand everything from the motion of planets to the operation of wheels and motors in machines. Through careful study of these physics principles, students develop problem-solving skills and gain deeper insight into how the physical world operates.

The practical applications extend far beyond the classroom. Engineers use physics concepts to design safer vehicles and more efficient machines. Medical professionals rely on physics principles for diagnostic tools like X-rays and MRI machines. Even sports scientists apply physics to help athletes optimize their performance. By mastering these fundamental physics concepts, students develop critical thinking abilities and prepare themselves for future careers in science, technology, engineering, and many other fields where understanding physical principles is essential.

Page 2: Advanced Mechanics and Fluid Dynamics

This page delves into more complex mechanical concepts including rotational motion, torque, and fluid dynamics principles.

Definition: Torque ττ = rF sin θ represents the rotational force effect, where r is the lever arm and F is the applied force.

Highlight: The moment of inertia formulas for different shapes are crucial for understanding rotational dynamics.

Example: For a solid sphere, the moment of inertia I = 2MR²/5, where M is mass and R is radius.

Page 3: Thermodynamics and Wave Motion

The third page covers thermal physics, heat transfer, and introduces wave motion concepts.

Definition: Heat transfer Q = mcΔT represents the basic equation for calculating heat energy transfer, where m is mass, c is specific heat capacity, and ΔT is temperature change.

Vocabulary: Efficiency EffEff in thermodynamics represents the ratio of useful work output to heat input.

Example: The period of simple harmonic motion T = 2π√m/km/k shows the relationship between mass and spring constant.

Highlight: Wave motion equations connect frequency, wavelength, and wave speed through v = fλ.

Page 1: Fundamental Constants and Basic Mechanics

This page introduces the foundational constants and basic mechanical formulas essential for physics calculations. The content spans from universal constants to kinematics equations.

Definition: The gravitational constant G = 6.673 x 10⁻¹¹ Nm²/kg² is a fundamental physical constant used in gravitational calculations.

Highlight: The speed of light c = 3.00 x 10⁸ m/s represents one of the most important constants in physics, serving as a universal speed limit.

Example: The quadratic formula x = b±(b24ac-b ± √(b² - 4ac)/2a appears at the beginning, showing its importance in solving physics problems.

Vocabulary: Kinematics refers to the branch of mechanics dealing with motion without considering its causes.

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.

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

Brad T

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🤍🤍

David K

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!

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
