Roller coasters[edit]

I wondered about the paragraph on amusement rides, where it is said that they usually don't pull over 3 g with some listed exceptions. However, according to "rcdb.com" and other coaster-related sources, almost every looping coaster on the world pulls about 4-5 g on entering the loop (e.g. the Vekoma Boomerang which is found in many parks around the world is said to pull 5.2 g on its first inversion).—Preceding unsigned comment added by 141.203.254.65 (talkcontribs)

External links modified[edit]

Hello fellow Wikipedians,

I have just added archive links to one external link on G-force. Please take a moment to review my edit. If necessary, add {{cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{Sourcecheck}}).

You may set the |checked=, on this template, to true or failed to let other editors know you reviewed the change. If you find any errors, please use the tools below to fix them or call an editor by setting |needhelp= to your help request.

Alpine skiing[edit]

In the "Typical examples" list "Typical to max. turn in Alpine ski racing" is listed as "5-12"G's. I did some digging and I wasn't able to find anything supporting much more than 3-4g's. And I have a hard time believing that a skier can pull g's like a fighter plane. Larry13 (talk) 20:50, 24 July 2016 (UTC)

Cars acceleration[edit]

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. --Angelo Mascaro (talk) 20:41, 26 January 2017 (UTC)

Acceleration, not force?[edit]

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.
