We start the new chapter on vectors.<\/p>\n\n\n\n
While a scalor is a quantity that has only magnitude, a vector is a quantity that has both magnitude and direction. We usually use directed line segment to represent a vector. The direction of the line segment, indicated by an arrow, represents the direction of the vector, and the length of the line segment represents the magnitude of the vector.<\/p>\n\n\n\n
Two vectors are equal if they have equal magnitude and are in the same direction.<\/p>\n\n\n\n
For vector additions, we study the triangle law and parallelogram law of vector additions.<\/p>\n\n\n\n
