I believe it depends on who you ask. In my experience, most physicists
and physics teachers don't bother with the distinction. Chemists and
mathematicians are more like to make the following distinction:
If it is a complete statement with the verb "=" (or in chemistry, the
"arrow" symbol), then it is an equation. If it is an incomplete
expression with no verb, then it is a formula.
Best wishes,
