Although it has been written for the American market, anyone with an ounce of common sense should be able to follow what is trying to be explained in the book. It is laid out as simply as possible, but do not try an read the explanations as you would a normal book. Get a pen and paper and do the examples as you go along. It makes them easier to understand.
I used the book as extra research as part of my completed engineering course, as a mature student and some of the items discussed in the book helped me gain a further insight to my Mechanical Principles unit and helped me pass an assignment or two. The last time I did any physics was over half my life ago so I was a little rusty and this was so simple that even me, as a blonde, could follow it. I will probably go back to it when trying to deal with the stuff in my up coming university course.
