<p>The 12th edition of Young/Freedman's University Physics, Vol. 1.</p>
<p>This is the first year that UM is using the 12th edition (which sucks for me because I tried selling back my 11th edition, and they didn't take it).</p>
<p>There's also a heavy, but cheaper in the long-run, edition that's Vol. 1-3...useful if you plan on taking Physics 140 or 160, 240 or 260, and 340 cause the same textbook is used for all three classes.</p>
<p>I doubt it really matters for 12th ed vs 11th ed. I had a math book, the solutions guide i had was one edition older, every problem was the exact same though. For Physics 140, your grade comes from in-class discussion, mastering physics, etc. You do a few problems from the book in class, but its just for participation. I think you could definitely get by on the 11th edition.</p>
<p>It looks like the guy who taught Physics 140 in the fall last year is teaching 240 this fall. But I will say that we never had to worry about anything in the books. We only did book problems during discussion where as long as you attended class you got the participation points.</p>
