That's the best explanation I have ever seen for centrifugation.

[@IainMcClatchie]

In NASCAR racing, the cars on the inside of the turn do not slow down to match angular rate to the cars on the outside of the turn. Instead, all the cars slow down (slightly) so that they are very close to the limit of adhesion of their tires. Lateral acceleration for all of them is approximately equal, and equal to v^2/r. Because the track is banked, some of that lateral acceleration is into the track surface, increasing traction and increasing the velocity that the cars can maintain around the corner. And THAT's why the bank angle changes across the width of the track. If the bank angle was constant, the cars on the inside would have an advantage: they'd actually have to go slower, but the shorter distance would mean they'd get around the corner sooner. You can see this in Formula 1 racing, where the tracks are not sufficiently banked. The inside lane has an advantage, and as a result, cars go around the track essentially in single file, there is little passing, and the race is boring. NASCAR tracks are banked so that the cars on the inside do NOT have an advantage. This makes it practical for cars to go around the turns side-by-side. That greatly increases the opportunities for passing, which makes the race more interesting. The optimal bank angle is complicated to derive, because there are many factors. The combined centripetal and gravitational acceleration on the cars does not point directly into the pavement. If it did, they'd be using none of the traction of their tires. There is also a substantial ramp from the straights into the curves, that varies across the width of the track. And finally, though I'm not certain of this, the racing is made more interesting by alternating a slight advantage from the right hand to the left hand side of the track, which changes which cars are favored over time. Track designers would achieve this by modulating the bank angle versus turn radius. Too much, and you get single-file F1-style racing, but a little, and you get some back-and-forth duelling.

[@billallen275]

Bingo! So, what do you think about the ideas of Mach and his analysis of Newton's Bucket? I think that the resultant forces are precisely as you describe and can all be attributed to the effects of angular velocity and restrained masses. The Earth if a little fatter at the Equator for the same reason. I think that Mach's ideas that the bucket and the rest of the universe's mass are involved, or responsible for the outward forces are wrong. Without friction and viscosity (e.g. friction on the liquid), the mass will remain motionless. The friction allows the rotating frame to impart forces to the bucket's contents and cause it to spin, too. But the mass wants to go in a straight line while being restrained. Vectors, like you said... Thanks.

Nascar tracks arent curved to account for constant angular velocity, obviously much too sharp of s rate of change for that to be true. Theyre curved to give the drivers options, so that a driver can avoid flying off the track at very high speeds, but also hhas the option to drive at low speeds if an ambulance or something needs to arrive.

[@rupertchappelle5303]

Reference frames allow one to ignore reality in order to con you about gravity. Like the you fall in an elevator, you are "weightless" but you still have mass, which is more important. When you land that mass counts for a lot more than it did at the beginning. At least you understand that gravity IS a FORCE and not a curvature. There are more curves than a parabola, you know? Like the ellipse and those tricky ones that would go up the side of that bucket and not be a parabola. (secant and cosecant for instance)

[@Raging.Geekazoid]

According to Einstein's general theory of relativity, there's no force acting on you while the elevator is free-falling. The fact that you have mass doesn't change that. When the elevator stops, the floor exerts an upward force on you. As far as we know in the early 21st century, gravity IS the curvature of spacetime. You can tell that it's not a force because you can't feel it.

[@frogkabobs]

What a bizarre and narrow minded take. Centrifugal force does exist in a rotating reference frame. This is because the rotating reference frame is accelerating away (centripetal acceleration) from the inertial reference frame. It’s called a pseudo-force because it arises from the reference frame being non-intertial, but it’s fully mathematically sound to work with. Rather, it would be difficult to go far in mechanics while only using inertial reference frames. Non-inertial reference frames are standard in a classical mechanics course and required in relativity (because there are no global inertial reference frames). There is nothing incorrect about the video’s use of centrifugal force being realized in a rotating reference frame here.

[@longsleevethong1457]

This is centripetal force. Not centrifugal.

[@frogkabobs]

No, it is centrifugal because they are using a rotating reference frame. If they had used an inertial reference frame, then things would have been in terms of centripetal force instead.

centripetal* acceleration edit: I started a nerd war

[@robertparker4884]

I believe centripetal acceleration is the acceleration the body undergoes towards the centre of the circle as a result of forces on the body from the car.

[@kryt7955]

In the reference frame of the object in circular motion, the apparent outward force _is_ centrifugal force. It is a pseudo-force. Centripetal force is the real center-seeking force in an inertial frame that causes the object to be in circular motion.

[@freshrockpapa-e7799]

No, it's centrifugal. In a rotating reference frame you do experience a centrifugal acceleration away from the center. Centripetal = towards the center. Centrifugal = away from the center

[@homieboi5352]

No, centrifugal force is not a real force. By making the reference frame the car, you’re observing an unbalanced force, rather the result of the body resisting the centripetal acceleration of the car and perceiving it incorrectly as a force induced by the driver themself. Even if your frame observes the driver moving seemingly on their own, that doesn’t mean you can pinpoint the force on them since physically they are not producing one

[@simonpedley9729]

@@homieboi5352but what is a real force? in a rotating reference frame, the equations of motion have centrifugal force. Thats all. No force is more real than any other.
