In this project, I would like to spawn a physics volume in a sea using C++, as I am manually modifying sea level in the code. The code below can spawn the physics level. However, it is not working correctly, as my character is supposed to swim whenever it overlaps with the Physics Volume. (IsSwimming from NavMovementComponent = false even after the character enters the physics volume, should be true instead).

It is an excellent free and open textbook for Physics for Engineering based courses and courses where we teach calculus-based Physics. It covers all topics that is taught in the 1st semester of calculus-based Physics courses. It shows algebra and calculus-based mathematics which is a great way to show students how Physics involves Calculus and how it can be different from when we use Algebra.
The format of this textbook is standard and professional compared to other calculus-based Physics course textbooks. Everything is organized in good manner and topics followed one after one that is related to each other.
The text used in this textbook are easy to follow. English used in it good. All explanations and examples follow step by step solutions and very easy to follow by a beginner. Figures and formulas written in it are consistent with chapters and covers all necessary figures and equations.
The chapters and topics are in right order and shown in the table of contents. There is a flow connection between chapters. Each chapter is explained clearly with small sections added in the form of figures, tables, examples and step by step solutions. There are sufficient exercise questions at the end of each chapter. The good thing that I like most that at the end of the textbook, there are answers to the questions those are asked at the end of each unit or chapter which helps students to see whether their answers are right or wrong and then discuss with their professors.
The organization of the textbook with each topic and chapter shown in it is excellent. No errors are found, and nothing seems missing either. Flow rate of this textbook is good. All chapters and units followed each other with concepts, equations, figures, and explanations.

The text covers all areas and ideas of the subject in deepth with examples. It also lists strategy, solution, check your understanding and significance sections. It does not do a good job in significance section in my opinion. There are much better examples that can be given for significance. Index and glossary are nicely listed referring to the section numberin alphabetical order at the end of the text. Incorporating more animations may help understand the subject.
The text provides good amount of clarity in terminology. However, the context can be better if there were more physical explanations of some of the terms used like dot product and cross product. Even though everything is correct mathematically, physical meaning of dot and cross products were not explained. I like how the vectors are both shown as vector on top of the letters and also bolt. It is easy to distinguish vectors from scalars.
The text is readable and have enough subheadings to allow smaller reading sections. Usually, a student attention span is about 20 minutes. The sections would appear to take about 20 min or less to read.
The topics in the text are presented in a bit different order than usual. The order some of the chapters are presented is a little confusing such as the separation of some of the chapters into two parts for the essentially the same subject matter. Separation of gravitation chapter into a single chapter is a little strange since we use gravity in many examples in previous chapters such as Potential Energy and Applications of Newton's Laws. I am a little confused as to why there are three University Physics volumes. Typically, introductory physics is separated into two semesters at universities. Having three volumes means second volume will be covered in both semesters.
It is a great textbook with in-depth example-problem solutions and opportunities to practice the knowledge learned. I like how the text lists the section learning goals at the beginning. The text also lists Strategy, Solution, Check Your Understanding and Significance segments. These segments help students develop problem solving skills and why what they learn is important. A lot of times, students question the importance or what they have to learn a particular subject. This is the part often instructors ignore when they present the material. Significance segment gives this opportunity. I believe it should be even more expanded in this book. Overall, it is a really well-written calculus based physics textbook that can rival other well established textbooks due to its in depth coverage and problem solutions.

The textbook covers all essential topics in standard University Physics course, in two big units: Mechanics and Waves and Acoustics. It is possible to cover all these sections during one semester course, because the chapters are not excessively long, but still manage to discuss all important topics in sufficient detail. The example problems are well chosen and help students understand the material, and end of chapter problems give additional practice opportunity to further master the topics.
The topics in the textbook are well established and it would be difficult to find a topic that is not relevant or needs an update in several years, all examples and general information is relevant to standard University Physics, now and in future.
The text is consistent, the only reason I am giving is 4 is because the significant digits in examples and end of chapter problems are not given in clear consistency: in some examples the significant digits are given in less accuracy and the answers are given at higher accuracy, and in others it is reverse. It would be very much advised to give all data in the examples and problems with numbers in scientific notation with clear number of significant digits, and expected to give answers following the standard rules of significant digits.

I had significant concerns about inconsistencies in the labeling of forces. For example, in figure 5.4 forces are labeled according to the type of force (weight, normal, friction). In figure 5.6 the forces are now labeled according to the other object involved in the force interaction (table, chair, floor) but the gravitational interaction between the person and Earth is still labeled weight which is not an object. These inconsistencies in labeling could be very confusing for a student who is learning about forces for the first time. I would prefer that the authors introduce forces as interactions from the beginning and then label them accordingly, similar to figure 5.16 but with the type of force interaction also included in the labeling.
I am of the opinion that energy should be presented before work. Otherwise, students are merely learning about work because their teacher says it is important. I think that conservation of energy should be used to motivate work as a way to quantify one mechanism of energy transfer. Other than this, I found the sequencing to be logical.
I don't find the textbook insensitive but I do not see much effort to support culturally relevant physics learning. The topics covered in this volume could foster learner engagement with important historically and culturally situated topics like: subjectivity and inclusion in physics, energy equity and energy justice. Perhaps future editions will incorporate these culturally relevant topics.
We are planning to adopt this textbook in the fall because we think it is the most comprehensive and well written open-source textbooks available for introductory calculus-based physics. As someone who has been actively involved in physics education research for the past two decades, I am a very critical reviewer so please bear that in mind when you are considering my comments above. This author team has made a significant and valuable contribution in creating this open resource. I would, however, recommend that the authors consult with an expert who is well-versed in PER if they undertake a substantial revision of the textbook.
I used this text for readings in my class, but my presentation of topics in the course differed immensely from the organization of the text (which is similar to most traditional physics textbooks). Yet, it was relatively easy to assign subsections of the text for readings and jump around to different chapters without requiring content from previous chapters.
There are only a few cultural or historical references, most of which are typical for an introductory physics course. The images and cartoon figures of people are overwhelmingly male. Much more effort could be made to include examples and figures of people from a variety of races and ethnicities.
