Exam Questions And Answers
anticommutative property - Answer-change in the order of operation introduces the
minus sign
/.antiparallel vectors - Answer-two vectors with directions that differ by 180°
/.associative - Answer-terms can be grouped in any fashion
/.commutative - Answer-operations can be performed in any order
/.component form of a vector - Answer-a vector written as the vector sum of its
components in terms of unit vectors
/.corkscrew right-hand rule - Answer-a rule used to determine the direction of the vector
product
/.cross product - Answer-the result of the vector multiplication of vectors is a vector
called a cross product; also called a vector product

axis and the vector, measured counterclockwise from the axis to the vector
/.displacement - Answer-change in position
/.distributive - Answer-multiplication can be distributed over terms in summation
/.dot product - Answer-the result of the scalar multiplication of two vectors is a scalar
called a dot product; also called a scalar product

/.orthogonal vectors - Answer-two vectors with directions that differ by exactly 90°90°,
synonymous with perpendicular vectors

resultant vector of many vectors
/.unit vector - Answer-vector of a unit magnitude that specifies direction; has no physical
unit
/.unit vectors of the axes - Answer-unit vectors that define orthogonal directions in a
plane or in space

vectors
/.vector product - Answer-the result of the vector multiplication of vectors is a vector
called a vector product; also called a cross product
