And yet nowhere in your calculations did you account for it. Bad form. D-.I know the angle gets smaller.

I never did, nor said, any such thing. Stop making shit up.I don't agree that you can multiply the angle by the acceleration to nullify the acceleration.
Nope. You just cannot admit you are wrong. You lose®.We're done. I don't care to continue this. You are deliberately lying.
Since when? Other than the fact that the centrifugal force is a pseudo force, not a real force, the definition of inertial force specifically includes both the coriolis (pseudo)force and the centrifugal (pseudo) force. It specifically refers to curved motion. And since when does F=ma not refer to curved motion? More important, when does anyone use that specific form of the equation (F=ma) mathematically when you have to differentiate...F = m (d^2r/dt^2). If you use radial coordinates for distance there's no problem at all making calculations for curved motion. Differential calculus is designed for such situations. Sin and Cos seem to work well when combined with radial coordinates and a defined, consistent frame of reference. Who told you these things?You need to throw out F=MA. It is not applicable to non inertial reference frames. Centrifugal force is not an inertial force. It is the only force that opposes gravity with an effect of complete cancellation.
Except that Newtonian Mechanics says there is, "the string", which cancels the other vector and keeps the ball roughly equidistant from the center.So there is no measurable inward acceleration opposing the centrifugal force. But that is just the observable fact. .
Because that ball desperately wants to take a tangent vector out of there. It is under continual vector changing.. The force is only present with rotation. .
That force is continually vector varying 360 degrees around the center of rotation. Pick the release point and you can a release in the direction of your choice.DarbyThe force is always directed way from the center of rotation. .
Negative mass:What the math model does suggest is that a similar model may exist for gravity. The only requirement would be that a negative inertial force would be necessary to push something in a negative direction. .
I don't really need negative mass. Since I prefer to use actual observations rather than mass which is pure fiction to begin with. But the observations do actually exist.Negative mass:Negative mass - Wikipedia, the free encyclopedia
"oppositely oriented acceleration for negative mass"
But it has been my observation that there are numerous existing facts that could be used with much more understanding. It's like telling me not to look. Naturally I'm going to look to see what it is that you don't want me to look at. Someone is trying to hide something. But why? It's like someone dropped a bomb on the knowledge base.Most folks, including myself are comfortable using the tools they were taught. F=MA, General Relativity, Special Relativity, etc.Regarding Math, I see it as a useful man made tool that attempts to describe reality and nature. Most of it's use in Physics is "close", but not perfect.
Yikes. Get rid of the "silly notion of mass" and replace it by weight? I really think that you're confused about what weight and mass are. They most certainly are not equivalent. Weight is a function of mass but mass is independent of weight. Maybe it's time to stop looking at "Mother Nature" (your personal myopic view of physics) and crack a textbook or two. As I've read your posts for the past 15 years it has always been apparent that you took, and never understood, high school physics but never advanced beyond that point. Your arguments against science come from alt-sci Internet sources that you choose to believe, not because they make any sense, but because they agree with your personal bias.Get rid of the silly concept of mass. Mother nature shows us the correct equation for F=MA should be F=WAk where W is weight and k is the proportional constant to make the units jive.
Lets use a gravitational freefall. On a planet like earth with one gee of acceleration. No atmosphere. Gravitationally the objects are weightless. But are they also inertially weightless? Inertial weight only exists in a direction opposed to inertial acceleration. So apply a force between the two objects and see. I see the experiment as a way to determine if gravitational weight and inertial weight are the same thing. You better pray they are different. And that makes my whole point for using existing fact over the fiction we are taught. Its the different types of weight that exist. Can we really mix them like we do with mass?Conduct a two body experiment where both bodies (you and a 1 ton lead ball) are in a state of uniform motion such that the motion is freefall. Are both bodies weightless? Yes (if the scale used to measure their weight is also in the same state of freefall - broad hint about the meaning of weight). Are they massless? Calculate the force necessary for you to push the lead ball away from you at some velocity using the correct equation F=ma. Then using your WAky equation where W=0 make the same calculation. Which one gives the correct answer?
