A vector is Associate in Nursing object that has each a magnitude and a direction. Geometrically, we will image a vector as a directed line section, whose length is that the magnitude of the vector Associate in Nursing with an arrow indicating the direction. The direction of the vector is from its tail to its head.   Two vectors are constant if they need constant magnitude and direction. This implies that if we have a tendency to take a vector and translate it to a brand new position (without rotating it), then the vector we have a tendency to acquire at the tip of this method is that the same vector we have a tendency to had within the starting.   Two samples of vectors are people who represent force and rate. Each force and rate are in an exceedingly explicit direction. The magnitude of the vector would indicate the strength of the force or the speed related to the speed.   We denote vectors mistreatment boldface as in an exceedingly or b. particularly once writing by hand wherever one cannot simply write in boldface, individuals can generally denote vectors mistreatment arrows as in a⃗ or b⃗ , or they use different markings. We can't get to use arrows here. We have a tendency to denote the magnitude of the vector a by ∥a∥. After we need to confer with variety and stress that it's not a vector, we will decision the amount a scalar. We are going to denote scalars with italics, as in an exceedingly or b.   You can explore the construct of the magnitude and direction of a vector mistreatment the below application. Note that moving the vector around does not modification the vector, because the position of the vector does not have an effect on the magnitude or the direction. However if you stretch or flip the vector by moving simply its head or its tail, the magnitude or direction can modification.
