first timer here and non english spoken so I might get few mistakes but but...
Question is about static equilibrium and about with clock and against clock principe. When figuring out momentum til a point first we define if its positive or negative. I understand that its our choice to define that as we find it best suited but how do we do that ? To use forces X and Y components when calculating forces we watch at their axes. If a force goes from higher to lower Y its negative, same for X. Here when calculating moemntum its not like that. This is basics I know but i really struggle to understand how to define (positive or negative ) forces when doing momentum...
Help will be highly appritiated...
