Model:


The model assumes $ \vec {A} $ and  $ \vec {B} $ are added together to form vector  $ \vec {C} $

$ \vec {A} $  + $ \vec {B} $ =  $ \vec {C} $


In its components of x and y direction

$  A_{x} $  + $  B_{x}  $ =  $ C_{x}  $

$  A_{y} $  + $  B_{y}  $ =  $ C_{y}  $

Changes made:


  1. i sort of made this on my own as the math is easy :)
  2. added ability to animate moving vector B tail to the head of vector A
  3. added showing of vector C after animation is done
