What does it mean that a mac app is 68K? Does it mean that it's made for the Motorola 68000 Macs? But 68K code can run on PPC, can't it? Then PPC must be"Backwards-compatible"? Am I right?

PowerPC chips are backwards compatible with 68k chips (not sure if its built in, or if its emulation)
68k software means that the software is made for the following processors:
68000
68020
68030
68040
There are 68060's but they were never used on macs so I dont know if 68k software works fully on them

Yup, and yep, I think it's just emulation, therefore 68k apps runs a little slower on PPCs than 68k's, and therefore there were often 2 versions of apps several years ago; 68k versions and PPC optimized versions
That was what I had seen before (before X) and suddenly I wondered what it really was!

yea, but still some of those old 68k apps run better and faster in classic than they did on my 68040 processor. they just take a little longer to launch.
and there were also a lot of fat apps - both ppc and 68k in one. you could save quite a bit of relative hd space by trimming them down to the version you needed with a third party utility.

Classic isnt really emulation though.
It isnt emulation because you are
1) Not emulating non-native hardware (OS 9 uses PPC architecture present)
2) You are not emulating an OS, it just is there. It runs concurently with OS X.
(at least from my understanding).
I remember when the transition was made from 68k to PPC -- first there were a couple of versions of an app, a 68k and a PPC and then they were made into FAT apps he he
There was an application that was called something like "trim" or something like that, that made FAT apps into whatever your machine was, so that there wasnt extra unecessary code.
