Which is the air resistance formula?

AI Thread Summary
The discussion centers on the confusion surrounding the correct formula for calculating air resistance. The equation presented, Y_1=(-m)/2k((T-mg-kv^2)/(T-mg)), is not clearly defined in terms of the variable to be solved. A commonly referenced formula for air resistance is F_D=(C_D ρAv^2)/2, but its applicability varies based on factors like the object's shape and speed. There is no single formula for air resistance, as it is influenced by multiple variables. Understanding these factors is crucial for accurately calculating air resistance in different scenarios.

I'm trying to solve this ecuation:
Y_1=(-m)/2k((T-mg-kv^2)/(T-mg))
I'm having some truble at finding a correct formula to find the air resistance. In my research through Internet I found loads of different formulas but I don't exactly know which is the correct one. In an other discussion on this forum I found this formula:
F_D=(C_D ρAv^2)/2
However, as I just mentioned I don't have it very clear.
Thankfully,
Jacob

your post is very confusing. Solve that equation for what variable? And is the question about "air resistance" a separate question? There is no one formula for air resistance- it depends upon a number of variables including the shape of the object moving through the air and its speed relative to the air.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
