PCS 211 Lecture Notes - Lecture 3: Unit Vector, Resultant Force
Document Summary
For a vector a with a magnitude of a, an unit vector is defined as ua = a /a. It points in the _____ direction as the original vector (a). Consider a rectangular box with sides ax, ay, and az. A = (ax i + ay j + az k) m. The projection of the vector a in the x-y plane is ___. A , is found by using the same approach as a 2-d vector: The magnitude of the position vector a can now be obtained as: yuan. The vector a can be defined as a = ax i + ay j + az k. The magnitude of the position vector a is a = (ax. The unit vector is defined as ua = a /a direction angles. These angles are measured between the vector and the positive x, y and z axes, respectively. Pcs211: note 3, pg 3 projection angles: yuan.
