chandra: I'm talking about the view from a person on the curve. to them the z-axis is always perpendicular to the curve. which is not always in the same direction as the force of gravity. that means that each component is directed away from the force of gravity by some angle. for example in 2D...
thanks for the help. now this may just be restating my question but its what has me going in circles
in 2D Fg is split into y= Fg sin(theta) x= Fg cos(theta). for an inclined plane. and theta is just the arctan(dy/dx)
however for a curve in 3D space Fg is split into 3 component forces. all of...
hello.
I'm looking for some general guidance as to which methods to use where.
i'm wanting to find the force vectors on an object as it moves along a general curve in a space (imagine a roller coaster). for example the parametric curve.
z=t
x=cos(t)
y=sin(t)I know i need to find the partial...
