Formula Acceleration 1 (FA1) was a single make, open wheel auto racing series. It was unusual in its field in that competitors solely represented their nation as opposed to themselves or a team, the usual format in most formula racing series.

FA1 was created in 2014 as the signature category in the Acceleration 2014 series of motorsport festivals. Rather than developing their own car, the series reduced costs substantially by using the Lola B05/52 which was used in the early years of the A1 Grand Prix series. They also continued to use the same 3.4 litre V8 engine built by Zytek Engineering. On 22 December 2014, it was announced that the series would be merged with Auto GP in 2015. This to ensure that at least 18 cars will participate in each race. It was also announced that the 2015 champion will be granted a Formula 1 test.[1][2] However, the season was halted after two rounds due to the lack of entrants.

Transcription

In this video, I want to talk a little bit about acceleration. And this is probably an idea that you're somewhat familiar with, or at least you've heard the term used here or there. Acceleration is just the change in velocity over time. Probably one of the most typical examples of acceleration, if you're at all interested in cars, is that many times they will give you acceleration numbers, especially for sport cars, actually all cars if you look up in Consumer Reports, or wherever they give the stats on different cars. They'll tell you something like, I don't know, like a Porsche-- and I'm going to make up these numbers right over here. So let's say that we have a Porsche 911. They'll say that a Porsche 911, they'll literally measure it with a stopwatch, can go 0 to 60 miles per hour. And these aren't the exact numbers, although I think it's probably pretty close. 0 to 60 miles per hour in, let's say, 3 seconds. So, although officially what they're giving you right here are speeds, because they're only giving you magnitude and no direction, you can assume that it's in the same direction. I mean, We could say, 0 miles per hour to the east to 60 miles per hour to the east in 3 seconds. So what was the acceleration here? So I just told you the definition of acceleration. It's change in velocity over time. So the acceleration-- and once again acceleration is a vector quantity. You want to know not only how much is velocity changing over time, you also care about the direction. It also makes sense because velocity itself is a vector quantity. It needs magnitude and direction. So the acceleration here-- and we're just going to assume that we're going to the right, 0 miles per hour and 60 miles per hour to the right-- so it's going to be change in velocity. So let me just write it down with different notation just so you could familiarize yourself if you see it in the textbook this way. So change in velocity. This delta symbol right here just means "change in." Change in velocity over time. It's really, as I've mentioned in previous videos, it's really time is really a change in time. But we could just write time here. This 3 seconds is really change in time. It might have been, if you looked at your second hand, it might have been 5 seconds when it started, and then my 8 seconds when it stopped, so it took a total of 3 seconds. So time is really a change in seconds. But we'll just go with time right here, or just with a t. So what's our change in velocity? So our final velocity is 60 miles per hour. And our original velocity was 0 miles per hour. So it's 60 minus 0 miles per hour. And then, what is our time? What is our time over here? Well, our time is, or we could even say our change in time, our change in time is 3 seconds. So this gives us 20 miles per hour, per second. Let me write this down. So this becomes, this top part is 60. 60 divided by 3 is 20. So we get 20. But then the units are little bit strange. We have miles. Instead of writing MPH, I'm going to write miles per hour. That's the same thing as MPH. And then we also, in the denominator, right over here, have seconds. Which is a little bit strange. And as you'll see, the units for acceleration do seem a little bit strange. But if we think it through, it actually might make a little bit of sense. So miles per hour. And then we could either put seconds like this, or we could write per second. And let's just think about what this is saying, and then we could get it all into seconds, or we could all get into hours, whatever we like. This is saying that every second, this Porsche 911 can increase its velocity by 20 miles per hour. So its acceleration is 20 miles per hour, per second. And actually, we should include the direction, because we're talking about vector quantities. So this is to the east. So this is east, and then this is east right over here-- just so we make sure that we're dealing with vectors. You're giving it a direction, due east. So every second it can increase in velocity by 20 miles per hour. So hopefully, with the way I'm saying it, it makes a little bit of sense. 20 miles per hour, per second. That's exactly what this is talking about. Now we could also write it like this. This is the same thing as 20 miles per hour, because if you take something and you divide by seconds, that's the same thing as multiplying it by 1 over seconds. So that's miles per hour-seconds. And although this is correct, to me this makes a little less intuitive sense. This one literally says it. Every second, it's increasing in velocity by 20 miles per hour. 20 miles per hour increase in velocity per second. So that kind of makes sense to me. Here it's saying 20 miles per hour-seconds. So once again, it's not as intuitive. But we can make this so it's all in one unit of time, although you don't really have to. You can change this so that you get rid of maybe the hours in the denominator. And the best way to get rid of an hour in the denominator, is by multiplying it by something that has hours in the numerator. So hour and seconds. And here, the smaller unit is the seconds. So it's 3,600 seconds for every 1 hour. Or 1 hour is equal to 3,600 seconds. Or 1/3600 of an hour per second. All of those are legitimate ways to interpret this thing in magenta right over here. And then you multiply, do a little dimensional analysis. Hour cancels with hour. And then will be equal to 20/3600. 20/3600 miles per seconds times seconds. Or we could say, miles-- let me write it this way-- miles per seconds times seconds. Or we could say, miles per second-- I want to do that in another color-- miles per second squared. And we can simplify this a little bit. Divide the numerator and denominator by 10. You get 2/360. Or you could get, this is the same thing as, 1/180 miles per second squared. And I'll just abbreviate it like that. And once again, this 1/180 of a mile, how much is that? You might want to convert to feet. But the whole point in here is, I just wanted to show you that, well, one, how do you calculate acceleration? And give you a little bit of a sense of what it means. And once again, this right here, when you have seconds squared in the bottom of your units, it doesn't make a ton of sense. But we can rewrite it like this up here. This is 1/180 miles per second. And then we divide by seconds again, per second. Or maybe I can write like this, per second, where this whole thing is the numerator. So this makes a little bit more sense from an acceleration point of view. 1/180 miles per second, per second. Every second, this Porsche 911 is going to go 1/180 of a mile per second faster. And actually, it's probably more intuitive to stick to the miles per hour, because that's something that we have a little bit more sense on. And another way to visualize it. If you were to be driving that Porsche, and you were to look at the speedometer for that Porsche, and if the acceleration was constant-- it's actually not going to be completely constant-- and if you look at speedometer-- let me draw it. So this would be 10, 20, 30, 40, 50, 60. This is probably not what the speedometer for a Porsche looks like. This is probably more analogous to a small four cylinder car's spectrometer. I suspect the Porsche's speedometer goes much beyond 60 miles per hour. But what you would see for something accelerating this fast is, right when you're starting, the speedometer would be right there. And that every second it would be 20 miles per hour faster. So after a second the speedometer would have moved this far. After another second the speedometer would have moved this far. And then after another second the speedometer would have moved that far. And the entire time you would have kind of been pasted to the back of your seat.

Technical specifications

All cars are mechanically identical and have been built with reducing costs in mind, which has led to an approximate price for the whole season of €450,000. FA1 will use the Lola B05/52, used in the A1 Grand Prix between 2005 and 2008.
