Andrew Duffy, the publisher behind many iOS app (Physics I HD ,Physics II HD ,ColorMixHD ,BallBounceHD ,Projectile ,ColorMix), brings Physics II HD with a number of new features along with the usual bug fixes. Physics II HD app has been update to version 1.8 with several major changes and improvements. App release that improves performance, provides several new options.
Ultimately, the plan is for this app to cover the Physics that is included in the second semester of a typical introductory college physics course (Physics I HD is a companion app with the first-semester material). It is also appropriate for high school physics. The app will essentially be an interactive Physics textbook. In addition to standard textbook material, the app also has simulations and animations, as well as movies.
Version 1.1 includes chapters 16 and 17 of the planned 14 chapters (these chapters will be numbered from 16-29, following on from Physics I). Chapter 16 covers electric charge, going through the basic model we use for charge, Coulomb`s law, and electric field. The emphasis is on the concepts, but there are also over 60 end-of-chapter exercises included.
Chapter 17 covers electric potential energy and electric potential. As with chapter 16, each section of chapter 17 has a simulation or an animation, and there are approximately 60 end-of-chapter exercises.
As more chapters are added, the cost of the app will rise (at the rate of about $1 per chapter). People who buy an early version of the app will get all the later chapters for free, as those chapters will come with the updates.
