I'm trying to work out the resultant forces when two circular objects interact.
Each object has known attributes: position; velocity; mass
The underlying formula needs to be able to calculate the force whatever the orientation of the positions are.
So, with two objects Obj1 and Obj2
Point1 = Obj2 - Obj1;
theta = arctan(Point1.x,Point1.y) - angle of the collision
sine = sin(theta)
cosine = cos(theta)
So now I need to change the coordinate system and work out the force then change back but i'm so lost =(((
Please help
