Difference between University Physics 13th and 14th edition?

[Justyn Oh]

Hi, I'd like to ask if anyone knows the differences between the 13th and 14th editions of University Physics by Young and Freedman? I have a copy of the 13th edition but a friend is taking a class using the 14th edition and he is considering borrowing mine or getting a new copy. Thanks in advance!

Have you friend check with his professor and see if the professor is having him do questions from the book itself or has another reason to want the 14th edition. If the professor is giving his own questions as homework, or using an online program like many nowadays do, then there may be no need to have the newest edition.
