Expert Answer:
Addition of vectors: Two or more vectors are added so as to determine their resultant.
Dot product of two vectors:
Dot product of two vectors is a scalar quantity and is given as A · B = AB cos ?. It is the magnitude of one vector times the projection of the other along the first
It is used to find whether the two vectors are perpendicular to each other or not because when the vectors are perpendicular to each other their dot product is zero.
Cross Product of two vectors:
Cross product of two vectors is a vector quantity and is given as A × B = AB sin ? n?.
It is the area of the parallelogram between them. The cross product of two vectors is a vector perpendicular to the plane containing vectors A and B.
It is used to find whether the two vectors are parallel to each other or not because when the vectors are parallel to each other their cross product is zero.
