Apparently Yukis crash on Saturday had like 68 G. Is that even possible with such the movement the car made?
And wouldnt that mean that he had a higher impact crash that Verstappen in Silverstone '21?
Here’s the thing, g force is a measure of acceleration or deceleration not impact, and that’s why when it’s used to compare big crashes it kind of irks me a bit (I have a post or an ask talking about g force in more detail but I can’t find it at the moment)
G force is literally a way of measuring acceleration and if you remember physics from school the standard units for that are m/s^2. The distance travelled divided by the time (in seconds) squared.
G force is wholly dependent on the distance the object travelled in the given period of time, when talking about crashes that is from the moment just before impact until the car is fully stationary, this is usually in the milliseconds. The quicker the deceleration the larger the g force number.
Also the G Force number that’s recorded can vary so much based on what sensor it’s taken from, there’s accelerometers/g force sensors on the bottom of the survival cell, in the drivers ear plugs, in their gloves and other places.
Also Ocon had a fairly low speed collision in Miami, but that was recorded at 56G because it was into concrete, which is not good at absorbing impact, hence much quicker deceleration than there would be into a tyre barrier for instance.
There’s also other things to take into consideration like the angle of the crash and what area of the car takes impact, for instance a car going forward into a barrier might record the same g force as a car that hit a barrier sideways or backwards, but it’s likely that the car that went in forwards would have been travelling faster initially (the car just decelerated slower because of the nose crumpling and absorbing impact)
Yes, by peak g force load Tsunodas was higher than Verstappen’s in Silverstone (51g), Ocon’s in Miami (56g) and Grosjean’s in Bahrain (67g), but all 4 crashes are very different and I think it kind of shows using g force as a measure of comparing crashes doesn’t really make sense.
Verstappen scrubbed off a lot of speed in the gravel trap, Grosjean had a front first collision which slows deceleration and Ocon had a sudden deceleration into concrete, whilst Tsunoda had a vertical impact.
So yeah I don’t like comparing g forces of crashes because it’s kind of pointless to do so because there are so many factors (types of barriers and walls increase or decrease deceleration time, different areas of the car absorb more impact than others)
Also it feels really weird to argue that one crash is worse than another
