WHY VECTOR AB+VECTOR BC = VECTOR AC BUT ANGLE IS MORE THAN 90 DEGREE.

Dear Rajan,

Adding two vectors A and B graphically can be visualized like two successive walks, with the vector sum being the vector distance from the beginning to the end point. Representing the vectors by arrows drawn to scale, the beginning of vector B is placed at the end of vector A. The vector sum R can be drawn as the vector from the beginning to the end point. The process can be donemathematically by finding thecomponents of A and B,combining to form the components of R, and then converting to polar form.

Best Of luck
