Physics: how do you write your v's to distinguish between Volume and velocity?

I use the uppercase/lowercase notation on a computer.  Only context makes it absolutely clear.  Using subscripts has its own issues .  eg Va or va MIGHT be velocity * acceleration.  Sometimes it is useful to define a quantity differently  "Let Z represent the volume of the item" so Z= A * L  This eliminates all confusion at the expense of sacrificing tradition.  But it sometimes is the only way to avoid a messy, easily misread, and confusing mathematical statement.

However since Yahoo has gone to only displaying the first three lines of an answer I have had to get rid of proper definitions for any simple problem.  The answer will not even get read if I do it "Right". Such is the dumbing down of our society.

I use a cap V for volume, and use an italic 𝑣 for velocity

Rarely do these get used together.
