This book is as good any of the Head First books I have purchased and used. In this case I used it to tutor some kids in the mechanics portion of physics. However, be sure to read the ENTIRE title - "Head First Physics: A Learner's Companion to Mechanics and Practical Physics". Thus the emphasis is on the mechanics portion of physics and the tone is practical in nature. There is enough rigor there, but the tone is conversational as in all of the Head First books by O'Reilly.
If you are looking for a tutorial on optics, acoustics, electricity and magnetism, and the rest of what composes a college freshman two-semester sequence on general engineering physics prepare to be disappointed - very disappointed. However, that is not what the author is selling you. I wouldn't recommend this as a stand-alone text - I don't think it is rigorous enough to be that. However, as a supplement to a standard college physics text on the mechanics portion of physics, I think it does a great job. It turns the incomprehensible into something that a good student willing to put forth some effort can understand and turns all of the talk of vectors and forces into an approach to mechanics problems that the student can use to attack most mechanics problems. For that purpose I highly recommend it. The student doesn't need to know calculus. The highest mathematics used is trigonometry.
