It's also perfectly acceptable (and preferred) if the code maps cleanly onto some existing mathematical terminology. 'v' is more readable than 'velocity' in the correct context.
The problem is that you get too close to the code you write, and make assumptions about its obviousness that simply aren't true. Far better to be explicit at the cost of a few extra keystrokes.
