Physics X is the most effective study tool for AP and intro college physics. It integrates free response questions, concise videos, quizzes, formula sheets, scratch pad and references to make the study process efficient, easy and mobile. <br><br>If you’re a busy student, finding enough time to study for each physics exam is a challenge. We have used the latest developments in educational psychology to build an app that maximizes productivity and helps you learn and do physics as quickly as possible. <br><br><br>WHAT’S INCLUDED:<br><br>-Over 500 multiple choice questions with detailed solutions. <br>These conceptual based questions help you to learn physics in a deep and intuitive way. They can all be answered without a calculator, pen or paper; making the study process as mobile as possible. <br><br>-Over 100 free response questions covering the most important topics from intro physics.<br><br>-Over 100 beautiful 720p videos which solve all the free response questions. <br>These concise videos were designed specifically for the mobile device and solve the problems clearly and systematically in order to develop your problem solving intuition. They are in a power-point-like format with narration.<br><br>-Extensive formula sheets accompany each chapter for quick access to all formulas from intro physics: including every formula on the AP formula sheet<br><br>-Fun and easy-to-use scratch pad allows you to do calculations on the fly, without the need for pencil and paper.<br><br>-Reference materials include: a list of fundamental constants, unit conversions, trigonometric identities, differentiation and integration rules and more.<br><br><br>WHO THE APP IS FOR: <br><br>- Students taking AP physics in high school<br>- Students taking intro physics in college<br>- Students preparing for the SAT physics subject test<br>- Students studying for the MCAT who need to review physics<br>- Anybody interested in learning physics<br><br><br>TOPICS COVERED:<br><br>Measurement and Units<br>Linear Motion<br>Projectile Motion<br>Newton’s Laws – Force<br>Energy and Work<br>Momentum<br>Rotational Motion<br>Torque and Angular Momentum<br>Gravitation<br>Static Equilibrium and Elasticity<br>Fluids<br>Vibrations and Waves<br>Sound<br>Temperature and Thermal Equilibrium<br>Heat<br>Thermodynamics<br>Electric Charge, Forces and Fields<br>Electric Potential and Capacitance<br>Currents and Resistance<br>Circuits<br>Magnetism<br>Electromagnetic Induction<br>Electromagnetic Waves<br>Reflection and Refraction<br>Interference and Diffraction<br>Optical Instruments<br>Special Relativity<br>Quantum Theory and The Atom<br>Nuclear Physics and Radioactivity<br><br>ABOUT: <br><br>Knowvio apps are developed for students by PhD students at the University of Chicago.<br><br>REVIEWS:<br><br>"This is the perfect "boost" for students who will be taking algebra-based introductory physics courses in college. With this app, they have an on-demand tutor who can coach them anytime, anywhere, whether it is at the bus stop or just before a test. The topics are thoughtfully chosen to illustrate the key concepts clearly, the graphics are elegant and concise, and Heinrich (the video narrator) does a fabulous job of explaining things! I will be heartily recommending this for all my physics students this coming semester!"<br>-John M. Beggs<br>Associate Professor of Physics<br>Indiana University<br><br><br>“Can't do without it!!<br>The last time I took physics was over 10 years ago in high school. Now I'm taking a university level physics 1 course. For me the toughest part is the math as I'm sure a lot of people share. This app gives you brief problems with simple numbers so that you learn to focus on the concepts and not just the numbers. Basically this app is helping me pass physics!!

If your on the fence, you should definitely buy it! It's 5 dollars for a huge number of questions that you can do every time you open the app. Great for finding your weaknesses and understanding where you need to focus.

I find this app very useful for me, I just use the app and take a look. the content of the application is very tight extensive and coherent. Its interface is designed very professional and convenient hands during use. I appreciate this app.

I bought and downloading the app hoping it would live up to my expectations created by the description. It did not. Most of the quizzes it provides are extremely basic including the FRQs. I am currently taking AP Physics and this is no where near the coursework. The best thing about this app used to be the formula sheet however it appears that they lost their domain 10 days ago and still have not fixed it. Complete waste of money

This app is really an effective study tool for learning physics. There are a lot of questions and other multimedia tools which help you study and learn college physics fast and easy.

The unneeded sentence on startup "This is a welcome core" has to be removed. Besides that, the app is good and educational but it has a glitch in the design that can be noticed on iPad where screens switch to vertical mode occasionally with pages not fit to the screen size and the inflated content go out of the frame which makes it impossible to use. If fixed this app would collect 5 stars.
