Very good book
Format: Paperback
My son borrowed the book from local library, he kept reading and became very interested in physics. He asked me to buy one so he could read it anywhere anytime. We are very satisfied with this book.

Really great basic/intro to physi
Format: Paperback
Purchased as a birthday present for my very smart 14 year old grandson. The book gives simple discussions about most basic elements of physics. I’m hoping it is not too simple but not too complex. First look tells me I made a good choice. I may buy another one just to have around the house for other grand kids. I’ll give an update after he gets into it a bit.

Looks good so far!
Format: Paperback, Format: Paperback
I’m a high schooler who has ADHD and I needed resources to clarify the material I learned from my classes. I’m also a visual learner, and this is AMAZING for my mode of learning. I flipped through the book and I’m literally so hyped to get into it. The illustrations are so cool. Never have I felt this excited to actually learn. Thank you Barron’s! I really hope they make more books like these for all subjects.
I will update y’all if I find anything in the book worth noting as I read through.

Interesting and informative
Format: Paperback
Seller gave an honest evaluation on condition of the book and it was received several days earlier than promised. I took Physics in college but wanted a quick review of some of the principles. The illustrations are good and take the place of a Physics lab, helping the reader to visualize the subject being discussed. The reader will have to look for a high school book to go into more depth, but this is great for an introduction or review of the subject.
