单词	parallelogram of vectors
释义	parallelogram of vectors A method of determining the resultant of two vector quantities. The two vector quantities are represented by two adjacent sides of a parallelogram and the resultant is then the diagonal through their point of intersection. The magnitude and direction of the resultant is found by scale drawing or by trigonometry. The method is used for such vectors as forces (parallelogram of forces ) and velocities (parallelogram of velocities ). See illustration. Parallelogram of vectors
