| The acceleration values in the table are average value, considering the ratio between the total change of speed (100 km/h) and the duration of the change. It would be more interesting to know the maximum acceleration: no car has a constant acceleration: the torque vs. rpm curve of the motor, the change of the gear rapport (if not an electric car) and the aerodynamical friction make the acceleration higher at the beginning and lower at the end. As I said, it would be more interesting to know the maximum acceleration: I suppose that the most of the other values are the peak value and not the average. --] (]) 20:41, 26 January 2017 (UTC) | |||

| == Acceleration, not force? == | |||
| It is inaccurate to say that g-force is an acceleration, not a force. The concept of g-force is the force acting on an object because of acceleration. If you were in a plane pulling 2 g, with a scale under your butt, it would read twice your weight. Electronic and spring scales measure force, not acceleration. ] (]) 21:36, 6 April 2017 (UTC) | |||

| The top illustration of a biplane seems to be claiming that an aircraft banking subjects the pilot to 2 Gs force due to the fact he is being acted on by earth's gravity and by the acceleration of the aircraft. Maybe I just read that wrong, but that's what it seems to say, and I don't think that's correct. Worse, it says "G increases as angle of bank increases", which is totally untrue. Angle of bank has nothing to do with the G force on the pilot. It's the rate of turn. Yes, frequently a tighter turn requires more bank, but other than that, no. You could fly a plane with a 90deg bank and not be "pulling" ANY Gs except for gravity trying to pull you straight sideways. It's banking and then pulling UP on the control column that causes the aircraft to turn. Increasing rate of turn is accomplished by pulling harder, or possibly by banking more. The G is a function of rate-of-turn and the speed of the aircraft. I'm no expert, but what is described there is misleading at best, because that's what it seems to be saying to me. ] (]) 04:46, 26 November 2017 (UTC) | |||

Problem
The title of the article "g-force" starts with small letter. JelloMello24 (talk) 20:14, 23 January 2023 (UTC)
Motorsports in the "typical examples" section.
We don't need formula 1 referenced 4 times, the only motorsports refs should be breaking G-force, and Kenny Braeck's crash. The Verstappen/Hamilton incident is clearly inflammatory if you're a fan of the sport, and the Grosjean example is superfluous. Perhaps the V8 example is 'good enough', but I stand by removing the two formula one crash references. Ruby.Boulton (talk) 02:51, 6 February 2024 (UTC)
Article does not proceed logically
In many places, this article jumps around from concept to concept, perhaps following the train of associations in the mind of a writer. This has led to inconsistent terminology, inconsistent logic, and difficult reading.
The slight helpfulness of knowing which topics are related in an author's mind doesn't seem worth it in this case. TooManyFingers (talk) 19:23, 29 May 2024 (UTC)
This article needs improvement
Should that banner thing at the top of the page that says "This article doesn't meet the standards for Misplaced Pages" or whatever be at the top? Theres 2 sections without any citations, and multiple needed citations Smirkjuice (talk) 23:06, 31 May 2024 (UTC)
Poor Sources for highest survived horizontal G forces.

This immediately resulted in Bräck's car impacting the catch fence that would record a peak of 214 Gs"
The citations for this are practically unrelated. The first source says it is "believed" he survived 214Gs, and does not have any citation. I couldn't even find anything about this in the second source. Derpyhoi (talk) 22:29, 25 July 2024 (UTC)
