Vector Analysis

Question 1

is a branch of physics or electrical engineering in which electric and magnetic phenomena are studied.

Answer 1

electromagnetics

Question 2

refers to a quantity whose value may be represented
by a single(positive or negative) real number.

magnitude only (speed, mass, tempt, distance)

Answer 2

scalar

Question 3

has both a magnitude and a direction in space. We are concerned with two- and three-dimensional spaces only, but vectors may be defined in n-dimensional space in more advanced applications.

weight, velocity, force, displacement

Answer 3

vector quantity

Question 4

▪ is a function that specifies a particular quantity
everywhere in a region.
▪ may be defined mathematically as some function
that connects an arbitrary origin to a general point
in space.

Answer 4

field

Question 5

are vectors lying in a common plane.

Answer 5

coplanar vectors

Question 6

a vector with unit magnitude directed( but not limited) along the coordinate axes.

Answer 6

unit vector

Question 7

2 vectors may be added graphically either by drawing both vectors from common origin and completing a aparallelogram or by tip to tail method

Answer 7

vector algebra

Question 8

in this coordinate system, we set up three coordinate axes mutually at right angles to each other.

Answer 8

rectangular coordinate system
