Is there a way to take a known path, all the existing forces/fields along it, and solve for a driving force function that results in an object moving along that path? but solving it without knowing the speed along that path, only the path itself, and maybe the total time taken from A to B along the path.
the reason I ask: normally force fields are given as functions of position,
and F=ma - so if acceleration can be related to the curvature of a path as a function of position, the problem will get a lot simpler.
The idea is to say
Fdriving(r) + Fexisting fields(r) = ma(r)
but I don't know a(r) outright, because it depends on the driving force, which I want to solve for. so can I take a path S that a(r) will lie on, and change this equation
Fdriving(r) = ma(r) - Fexisting fields(r)
into this one
Fdriving(r) = kC(r) - Fexisting fields(r) ?
is there some relation between acceleration and Curvature of a path/trajectory, C?
or is this even possible?
thanks for any ideas
