Detailed explanation-1: -When displacement vectors are added, the result is a resultant displacement. But any two vectors can be added as long as they are the same vector quantity. If two or more velocity vectors are added, then the result is a resultant velocity. If two or more force vectors are added, then the result is a resultant force.
Detailed explanation-2: -Triangle Law of Vector Addition Draw a line AB representing vector a with A as the tail and B as the head. Draw another line BC representing vector b with B as the tail and C as the head. Now join the line AC with A as the tail and C as the head. The line AC represents the resultant sum of the vectors a and b.
Detailed explanation-3: -Addition of Vectors The vector that gets connected to the tail of the first to the head of the second is the sum of vector c. The vector addition obeys the law of associativity and is commutative.
Detailed explanation-4: -The sum of two or more vectors is called the resultant. The resultant of two vectors can be found using either the parallelogram method or the triangle method .
