Physics Introduction To Vectors Part 2 Youtube The video is a basic introduction to coordinate systems and vector components. the following topics are addressed: defining a coordinate system, reference. Addition & subtraction of vectors. method 1: triangle method. method 2: parallelogram method. as we have discussed before, a vector is just a scalar pointing in a specific direction. it is represented by an arrow of length equal to its magnitude and pointing in the direction of the vector. the "line part" "scalar part" of the vector is called.
Physics Introduction To Vectors Part 2 вђ Artofit A scalar is a physical quantity that can be represented by a single number. unlike vectors, scalars do not have direction. multiplying a vector by a scalar is the same as multiplying the vector’s magnitude by the number represented by the scalar. vectors are arrows consisting of a magnitude and a direction. Vector knowledge is very important in physics 2, as it is the basis for nearly everything we do. most scientific disciplines don't rely as heavily on vector forms as physics. because physics is so focused on the motion of different things (people, particles, objects), vectors are an integral part of physics. In general, when a vector →a is multiplied by a positive scalar α, the result is a new vector →b that is parallel to →a : →b = α→a. 2.1. the magnitude |→b| of this new vector is obtained by multiplying the magnitude |→a| of the original vector, as expressed by the scalar equation: b = | α | a. 2.2.
