About
This interactive Gravity Advanced Level Physics chapter textbook works on both Android and iOS, offering a gorgeous, full-screen experience full of 15+ interactive simulations even 3D are available at the 3D geostationary orbits simulation, animated pictures and static photos, and links to videos on Youtube. No longer limited to static pictures to illustrate the text, now students can play and conduct mathematical modelling pedagogy developed by the Author using the Open Source Physics/Easy JavaScript Simulations. They can flip through a book by simply sliding a finger along the bottom of the screen. Highlighting text, taking notes, searching for content, and finding definitions in the glossary are just as easy. And with all their books on a single device, students will have no problem carrying them wherever they go.
The content are originally based on lectures notes from Yishun Junior College, Singapore.

Survey Data
| Survey results on Gravitation ebook from JC1 seniors workshop on 15 Oct 2015 | ||
| Sample size: | 15 | |
| S/no | Questions | Answers |
| 1 | How useful is this ebook, on a scale from 1 - 10? | 7.27 |
| 2 | Would you use this ebook, on a scale from 1 - 10? | 6.4 |
| Why? | Useful for easy visualisation | |
| Learning become more interesting [2] | ||
| Better than boring lessons as this is more interactive [2] | ||
| Very interesting and good for concept but once is enough for understanding | ||
| Easier to visualise as compared to paper but may not be able to understand fully the use of each function | ||
| Prefer lecture notes but this may come in handy when I need clarification | ||
| Might be difficult to use but it is helpful for students to understand better | ||
| Useful but boring | ||
| Might not have additional time to use it | ||
| Not a system I am used to | ||
| A little time-consuming | ||
| I may not know how to use certain SIM and hence not using it | ||
| The SIM is repetitive and the content is heavy | ||
| 3 | Should we replace lecture notes with this ebook? | Yes [3]; No [12] |
| Why? | Definitely gives a clearer explanation | |
| It is more interactive | ||
| Environmentally friendly and useful | ||

| It should be supplementary/additional learning material, not to replace notes [5] | ||
| Lectures notes are more informative | ||
| 4 | Which is your favourite SIM? | 3D Geostationary satellite model [14] |
| Binary stars model | ||
