(called a unit vector) parallel to the x axis and in the positive direction, and j to be a vector of length 1 (another unit vector) parallel to the y axis and in the positive direction. i j O A C Diagram 8 From diagram 8, * OC= * OA + * AC. The vector * OA is parallel to the vector i and four times its length so * OA= 4i. Similarly * AC= 3j. Thus the vector * OC may be written as * OC= 4i+3j... 3 References used in compiling these charts and tables are listed below in the order of “most usage”. 1.

**Physics with Calculus/Mechanics/Scalar and Vector**

Vectors enter physics in two distinct forms. (1) Vector A may represent a single force acting at a single point. The force of gravity acting at the center of gravity illustrates this form. (2) Vector A may be deﬁned over some extended region; that is, A and its compo-nents may be functions of position: Ax = Ax(x,y,z),and so on. Examples of this sort include the velocity of a ﬂuid varying... where bx=(1,0) and by=(0,1) are unit vectors in the directions of increase of x and y, respectively, and ( v x ,v y ) denotes its components. In terms of its components ( v x ,v y ), the magnitude of the vector v is

### The resultant is the vector sum of two or more vectors. It is the result of adding two or more vectors together. If displacement vectors A, B, and C are added together, the result will be vector R.

- • Draw a vector as a line with an arrowhead at its tip. • The length of the line shows the vector’s magnitude . • The direction of the line shows the vector’s direction .
- The resultant is the vector sum of two or more vectors. It is the result of adding two or more vectors together. If displacement vectors A, B, and C are added together, the result will be vector R.
- Vectors are quantities that carry two pieces of information, a magnitude and a direction. Sometimes we want to use a vector in a calculation, but we only want to use the direction information of the vector.
- The quantities that come across in physics is referred to as a physical quantity. Example: Mass, length, time, temperature, etc., Whenever we measure a physical quantity, the measured value is always a number. This number makes sense only when the relevant unit is specified. Thus, the result of a measurement has a numerical value and a unit of measure. For example, the mass of a body is 3 kg
