Vector addition is used to add two vector components. Let the vectors be A and B then C = A + B.
A vector can be specified either by its magnitude and direction or by its components. The vector is in ijk format. That means A = a1i+b1j+c1k and B = a2i+b2j+c2k . The co-efficient of i ,j and k are added separately to form the vector C = a3i+b3j+c3k. For each vector A there exists a negative vector. This vector has direction opposite to that of vector a but has the same magnitude; it is denoted by -A. This worksheet help you to understand how to perform vector addition.
Vector properties:
The vector addition obeys the following properties such as Commutative and Associative Law
Vector Commutative Law A + B = B + A
Vector Associative Law A + (B + A) = (A + B) + C
The formula for Vector Addition C = A + B
Example problem:
Calculate the vector addition whose inputs are
A = 1i+2j+3k
B = 4i+5j+6k
Then the resultant vector C = A + B
C = (1+4)i+(2+5)j+(3+6)k
= 5i+7j+9k
The resultant vector is 5i + 7j + 9k
