**A Premium Physics site for tutorial videos and online physics courses**

A small example of an interesting physics tutorial video snapshot is given below. The famous proverb, “A picture is worth a thousand words” is very much applicable to physics. The online Physics course shows hundreds of pictures which helps easy and fast understanding of concepts and equations for young students. It may be quite difficult to understand friction concept and its vector direction from a typical textbook or online tutorial course, but physicsmodels.in makes it so much easier and faster to understand. In the specially designed tutorial videos and pictures in physicsmodels, the concepts come to life really fast.

In this online course, even a junior beginner student may be able to grasp physicsquickly. Students save energy and many hours of precious time.

**Remembering concepts**: — It is commonly known that while students may understand concepts while reading a textbook, the problem is how to remember them later, especially at the time of exam, without very strenuous revision. That’s where physicsmodels comes in to help.

Each video is specially designed to make alasting visual impression on the mind of the reader. This makes it possibleto recall the concepts and equations in an exam with least amount of effort.

Effort minimization is a aim of this online course and Physics tutorial videos.

The key is the high quality and brilliant clarity of 3D pictures in www.physicsmodels.in. For example, how can one forget the above image of a 3D robot walking on sand?

Such tutorial videos make things easy to keep physics chapters in mind for a long time as compared to standard ways of learning physics.

Everyone is looking to understand concepts quickly and easily. Nobody has time and energy to read only one chapter for hours and hours with many doubts and questions regarding the concepts. It can be very frustrating to try to understand what is written, when it is not explained clearly and logically.

It is needed to have a top-class tutorial to understand the concept physically, and then apply equations. After going through physicsmodels, it becomes easier to apply theory in solved problems.

As the creator of this attractive and easy-to-read online course, I am proud to say that thousands of students love the experience of learning physics with 3D Models and 3D Animations. The word “model” here refers to digital computer generated models. The feeling it gives to a student is somewhat like standing in a Physics Laboratory and seeingan experiment. Each video is compacted, with accurate and scientific statements in an informal style of communication. That helps listen to the videos and saves a lot of student’s time and energy.

**Remembering equations**:

The next important thing is to learn the equations, and also how they are derived. The derivation of an equation is not so simple. It needs heavy basics, and a strong mastery of concepts and a gradual step by step way to reach the final equation. It may look easy when we are looking at a textbook, but it may be very difficult to write the same steps by oneself. That’s one of the main challenges with physics teaching and physics learning. Every step must be taught in a crystal clear way without ambiguity and with logic that convinces the student.

The www.physicsmodels.in offers videos combining brilliant clarity in 2D slides. The 2D slides is a must to see the equations .In this online course, several Tutorial Videos with voice explanations take a student through , in a step-by-step manner.

An example 2D slide is shown below:-

The colour combinations, the explanation, the look & feel, the whole package and experience in totality, is the crux of the online course. The videos with voice explanationsare designed for readers to understand why the equation is the like this, how it can be derived from scratch, and so on.

The site offers many tutorial videos covering chapters for Class X to XII.

While all may not have access to the best teachers, one can login to www.physicsmodels.in . Tune into the site, relax, sit back, and listen and see Videos.

Students worldwide are finding this website extremely useful and unique as a self-learning online course tutorial for high school courses. The sequence of chapters in this online course isin approximately the same order as normal textbooks. An example image is given below of the arrangement of chapters:

**Maths starters**: The 1st chapter — Maths Starters, that you can see above, is important as it helps students to be comfortable with physics chapters that come later, and which may use Differential equations, Integration, complex graphs and so on. This online maths course is really attractive, there are lots of videos having 3D Images, 3D Animations, and an extremely simple and logical explanation of to students what exactly is Differentitation and Integration.

**Self-Evaluation**: Students can alsodo self-evaluationby going through solved problems at the end of each chapter. (More videos are being added for solved problems).

**Solved problems**: This online courseincludes solved problems to help in mastering the theory concepts. Solved problemsare important to increase our understanding of physics concepts. One should first learn theory, and then go to solved problems, and many times one can again come back to theory to re-understand the concept better. This loop is good and important for students.

**Online course coverage**: This online course has 47 chapters which cover nearly everything required for syllabus for Class X to Class XII, as well as many competitive examinations like IIT JEE, AIEEE .There is no forced time limit to complete chapters.

**Self-evaluation test questions**: Test questions /quiz are added to a few of the chapters — placed at the end of each course. A test can be attempted 10 times, and this ensures a stronger revision, to result in a high confidence to a student. The marks scored areprivate to user. (others cannot see)

More tests are being designed and would be added to further chapters in future in a phased manner.

Examples mentioned in this paper,are examples (please visit the online course and video tutorialsfor more details):- Motion along aplane, Motion on an Inclined plane, Inertial and Non-Inertial Frames of Reference, Gravitation, Earth moving around the Sun, Friction, Inclined Plane, Torsional Vibration, Pascal’s Law, Hydraulic Lift, Archimedes principle, Thermal Conductivity, Magnetism, Magnetic Field around a current carrying wire, Electric Field, Capacitors, Van De Graff Generator, Biot-Savart Law, Electromagnetic Induction, Faraday’s Laws, Transformer, DC Motor, AC Generator, Wave Motion, Sound, Beats, Open and Closed Column Vibrations, Mirage Effect , Prism and Refraction, Young’s Slit Experiment, Light Diffraction, Relativity.

**Quality above Quantity**:

At www.physicsmodels.in , we believe that Quality of explanation is more important than Quantity or length of explanation for many pages. The video tutorial durationhas been kept just right, around 3 to 5 minutes on an average.Students first seetutorialvideosas a first step , thengo through solved problems videos as the second step.

The high quality videos experience in this online course leaves a lasting impression in the students’mind. That’s a key differentiator of www.physismodels.in, as compared to many other tutorials. Students can learn all the concepts and gain confidence in a rapid way,and as a good practice, get into textbooks and perfect the understanding by doing more exercises and solved problems.

I am confident that students in India as well as all over the world will benefit greatly from this online coursewith video tutorials.

Thank you.
