After I explained to Maltz what you'd said about flipping and tipping, he said that we should say that qaw' means "tip over" and qaw'moH means "tip over, knock over, knock down."

You'd use qaw' if the object [i.e. "thing", not grammatical object] tipped over on its own accord or seemingly on its own accord (even if there is a known cause). If you lose your balance, you may qaw' (in English, in this situation, you'd probably say "fall" or "fall down" or "fall over" rather than "tip over," but it's the same sort of action). Without remediation, the Leaning Tower of Pisa might qaw' one day. A few years ago, we had an earthquake here. I wasn't home at the time, so I didn't know what kind of damage (if any) to expect when I got home. It turns out, almost everything was fine! Only one little statue qaw'ed.

So what the rebels do is qaw'moH the cars (like some folks are doing in the US right now).
