I don’t know if it’s significant but on the carrier the arresting system is going 25-30 mph. The ship is moving.

Again, maybe not enough to really matter, but enough to at least take into consideration.

I imagine it means that the arresting system is being tested to greater limits on the ground than at sea, all else being equalish?

Since the relative speed of the aircraft to the ship will be reduced.

That is all correct. I have flown gliders and studied physics :)
