8.3.2 Subtraction of Vectors The subtraction of the vector b ˜ from the vector  a ˜ is written as  a ˜ − b ˜ . This operation can be considered as the addition of the vector a ˜ with the negative vector of b ˜ . Therefore a ˜ − b ˜ = a ˜ … Read more

8.3 Addition and Subtraction of Vectors 8.3.1 Addition of Vectors 1. The addition of two vectors, u ˜  and  v ˜ , can be written as u ˜ + v ˜ . The result of this addition is a vector which is called the resultant vector.2. When two vectors with the same direction is added … Read more

8.2 Multiplication of Vector by a Scalar and the Parallel Condition of Two Vectors 1. When a vector a ˜ is multiplied by a scalar k, the product is k a ˜ . Its magnitude is k times the magnitude of the vector a ˜ . 2. The vector a ˜ is parallel to the … Read more

(A) Definition of Vector and Vector Notation 1. Vector is a quantity that has both magnitude and direction. 2. Scalar is a quantity that has magnitude only. 3. A vector can be presented by a line segment with an arrow, known as a directed line segment. (B) Equality of Two Vectors 1. Negative vector of … Read more
