Is there any difference between these two different ISBN University Physics 13th Ed?

9780321775337 is the newest while 9780321675460 is mildly older I think. they are both 13th edition though. They have different covers but will I have any problem if I get the older one that is MUCH cheaper?|||Different ISBN for a same book means revision or newer edition. The newest will have most current information. Usually the substance will not be much different but the examples given will be different. Also, some items or topics will be rearranged. It is therefore prudent to use the newest edition if you are required by your educational institution. If you just want for reference purposes, then it is ok to get the older edition.
