I’ve always thought the the two terms mean the same thing. However, in an edition of the previous series of “University Challenge” (a British university quiz show hosted by Jeremy Paxman), when one of the two contesting teams gave “acceleration due to gravity” as an answer to one question, the answer was disallowed by Jeremy Paxman because the answer on his card was “acceleration of free fall”. :?
I was totally stunned.
Fortunately the team that had that answer disallowed won by a comfortable margin in the end and so there wasn’t a fuss over that particular question. Well then, is there really a technical difference in sense between the terms “acceleration of free fall” and “acceleration due to gravity”? Have I been right all along to consider both expressions as synonymous with each other? :|
