This isnt a homework question (im not in school) but its nearly one for a Theomech class, or maybe just dynamics. Maybe I'm just not seeing it.(adsbygoogle = window.adsbygoogle || []).push({});

Assume you have a hill thats defined by some part of a function y=f(x) (like exponentially decreasing, or a sine wave)

and you put an object on top and let it move down the curve.

assume no friction, there is some gravity force in the y direction only.

What are the independent forces of the object at a given x direction?

so im looking for Fx(x,f(x)) and Fy(x,f(x)) so get the force given some euation describing the curve and a position.

Would I use lagrangian mechanics to pull out the accel in each direction? or what...

thanks
