Alright, let’s talk about them fast cars, the ones that go zoom-zoom real quick. You know, the kind that young folks like to show off in. I heard someone talkin’ ’bout how fast one of them goes, said it goes from standin’ still to 95 somethin’ or other, kilometers they called it, in just a few seconds.
Now, I ain’t no fancy engineer or nothin’, but that sounds mighty fast to me. Imagine that, sittin’ still one minute, and then whoosh, you’re flyin’ down the road the next. Reminds me of them rockets they shoot up into the sky, only this one stays on the ground, mostly anyways.
They were talkin’ about somethin’ called “acceleration,” sounds complicated, but it just means how quick somethin’ speeds up, I reckon. Like when you step on the gas in your old pickup, only these sports cars, they do it a whole lot faster. They said somethin’ about meters and seconds, all that stuff makes my head spin, but the bottom line is, these cars are quick.
So how fast is this “acceleration” they talk about?
Well, from what I gathered, if one of them cars goes from zero to 95 kilometers per hour, that’s like, real fast, in say, 6.2 seconds, you gotta figure out how much it speeds up every second. That’s the “acceleration” part. They do some fancy math, changin’ the kilometers to meters and the hours to seconds. Sounds like a lot of work to me, but them smart fellas figured it out.
- First, they change that 95 kilometers per hour to meters per second. I ain’t sure exactly how they do it, but it involves multiplyin’ and dividin’, I think. They get somethin’ like 26.39 meters per second, or maybe a little more or less dependin’ on how fast the car is.
- Then, they take that number and divide it by the time it took to speed up, that 6.2 seconds. That gives them the “acceleration” in meters per second squared. They said it’s around 4.246 or somethin’ like that. Sounds like a bunch of numbers to me, but it means the car is really jumpin’ when you step on the gas.
Now, some of them cars are even faster, they said. Some can do it in 4.3 seconds, or even 4.5 seconds. That means the “acceleration” is even higher, which just means they speed up even quicker. I tell ya, it’s a wonder them young folks don’t get whiplash drivin’ them things.
And what about the engine?
They were also talkin’ about somethin’ called the “force” of the engine. Now, I know about engines, my old pickup’s got one, but this is different. Seems like the faster the car speeds up, and the heavier it is, the more “force” that engine needs to have. They were sayin’ somethin’ about an 850 kilogram car, that’s pretty heavy, and goin’ 95 kilometers per hour. That engine’s gotta be workin’ real hard to get it movin’ that fast.
It’s all about speed and time
They also talked about another car, going to 33 meters per second in 7.2 seconds. See, it’s all about speed and time, how fast somethin’ goes and how long it takes to get there. They can figure out how far the car went too, using more of that fancy math. It’s all connected, I guess.
So, there you have it, a little bit about them fast cars and how quick they go. It’s all about speed, time, and how fast somethin’ can speed up. Me? I’ll stick to my old pickup, it might not be fast, but it gets me where I need to go, and that’s good enough for me.
They also said somethin’ about the “initial velocity” bein’ zero, that just means the car starts from standin’ still. And the “final velocity” is how fast it ends up goin’. See, even an old lady like me can understand some of this stuff, even if I don’t use all them fancy words.
And that “average acceleration”? Well, that’s just the, you know, the in-between speedin’ up, not too fast at first, then faster and faster, kinda like when you’re pourin’ molasses, starts slow then picks up speed. They measure it in somethin’ called “meters per second squared,” sounds complicated, but it just tells you how much faster the car is goin’ every second.
Anyways, that’s all I got to say about them fast cars. They’re fast, that’s for sure, and them engineers know a whole lot about how they work. Me? I’m just happy to watch ’em go by.
