This segment transitions from theoretical concepts to practical, real-world engineering basics.

Abbott transitions from visible mechanics to molecular mechanics by exploring thermal energy:

This public link is valid for 7 days and shares a thread, including any personal information you added. This link or copies made by others cannot be deleted. If you share with third parties, their policies apply. Can’t copy the link right now. Try again later.

Because this textbook has been a standard in international curricula for years, physical school libraries and local public libraries almost always carry multiple copies.

While the full textbook is under copyright, many free, legal physics resources are available online that can supplement its content. While it doesn't host Abbott's book, the Internet Archive (archive.org) is a treasure trove of other public-domain physics texts, including some by M. Nelkon, Abbott's co-author.

Generally, no. Downloading a full PDF of a copyrighted textbook without paying for it is copyright infringement, unless the copyright has expired (which it hasn't; life of author + 70 years in most jurisdictions).
