2D Collisions A 2 Collision is equal to two simultaneous 1 Collisions on the and axes, respectively. D D x y This means that you will first find the and x y components of each (vector) mom entum involved in the collision and THEN apply conservation of (vector) momentum twice - first on the axis and second on the axis: x y 1 : : ix fx i x x axis p p x axis p = G G G 2 1 2 i x f x f x p p p + = + G G G : iy fy y axis p p = G G 1 2 1 2 : i y i y f y f y y axis p p p p + = + G G G G
