NewtonCalculateSpringDamperAcceleration... what is it and what does it do, how do i use it, what are the params, i was unable to find any exact info on this api, i'm interested to see if i can use it for my current system.

It calculates the accenrlation fo a mass/spring/damper system

normaltly the instanteneus acceleraion if given by
A = - k0 /m * (x - x0) - k1 * v

by taht will be teh accelration of teh system and poistion x, and velocity v
the acceleration calculated by thqt equation if very vey unstable wun integrated by a first order diffrencial equation.

if instead the accerlation is calculated at teh end of teh time step the.
teh a new paremep is needed to predicet the derivative if the system, thsi si what is call implicit system
and you get and accelerating that is unconditionally stable, and you cna trea just like the above equation
