a few moments ago = a few minutes ago?
Or it is shorter than a few minutes?
I think it means different things to different people. I might say 'a moment ago' (more than I would say 'a few moments ago') if something happened a few minutes ago, for example if I want to emphasise to someone that they just missed seeing someone/something.
"You won't believe who I saw on the other side of the street a moment ago!"
has a greater urgency than:
"You won't believe who I saw on the other side of the street a few minutes ago!"
A few minutes ago is history; a moment ago is still tantalisingly close.
This is an amusing topic. From what I've learned, a few moments ago is typically regarded as an event that most recently occurred. Depending on the person's perception of time, a few moments ago could either be a few seconds or several minutes. As such, there are no concrete definitions.
"A moment ago" and "a few moments ago" are synonymous.
