You are riding a roller coaster your velocity is 13 feet per seconds . are you moving up or moving down

Remark

You can't really tell. Somewhere you have to declare which way is up (or down)

You also have to declare whether up is plus or minus. Without that declaration, a velocity like 13 feet per second is meaningless.

So if you know something about up or down or plus or minus, please state it.
