The magnitude of vector is defined as (2) The unit direction can then be found for the vector by dividing (1) by (2) Vector decomposition. Let us consider a more simple, 2-D vector in the - plane, . The components of can be decomposed geometrically by the use of trigonometric identities for a right triangle.

Unit vector is a vector whose magnitude is 1 and point is a particular direction. Without loss of generality, we can assume to be three distinct unit vectors along the x, y, and z-axis relatively. Then, and . Also, In cylindrical coordinate systems, a vector, where are the unit vectors of the coordinate system.

Unit vectors: a vector of unit length and is calculated by dividing the vector by its own magnitude. Null or Zero vectors: a vector with zero magnitude (zero length) and an unspecified direction. Negative vectors: two vectors having the same magnitude, but opposite directions. Under symbolic (also called Gibbs) notation, vectors are designated by

Work, a scalar quantity, is the product of force and displacement, both vector quantities (W = F • d). The unit for work is the joule (J). Suppose vector a represents a force of 3i + 4j newtons that is applied to a model train on a track. Vector b represents the train’s displacement and is equal to 12i + 5j meters.

Similarly, vector . B. would be written as -3.8 . i + 1.4 . j. Example 1: Express the vector 4.2 m @ 132( in unit vector notation. (Answer is at the end of this handout.) ADDING VECTORS. It is easier to add vectors by first expressing them in unit vector notation and then finding the sum of the individual components. For example, to add vectors ...

In this unit, you will learn a new method to describe the motion of objects that do not travel in a straight line (two-dimensional). Vector – a quantity that represents both magnitude and direction. Give an example of a vector quantity for the following: Displacement – 5 meters East. Velocity – 50. m/s South. Acceleration – 4.7 m/s2 West
