PPT-Scalars vs. Vectors

Scalar quantities have only a magnitude amount Vector quantities have a magnitude and a direction We represent them as arrows Distance d the separation between two points . 1 Scalars and Vectors is a number which expremay or may not have units associated with them.Examples: mass, volume, energy, money s both magnitude and direction. The magnitude of a vector is a scala Math 185 Vectors d) neither, because it is a direction only (Careful! You might think that the 15 Which of the following is the odd one out?. Mass. Speed. Force.

I . used four different files to teach. my . students. . about. . vectors. I have used these files several times but every time . At the end of yesterday, we addressed the case of using the dot product to determine the angles between vectors. Similar to equations from algebra, we can talk about relationship of vectors as well. Parallel. vs. Vectors. Scalars – a quantity that only needs a magnitude (with a unit) to describe it. . Ex:. . Vectors – a quantity that needs a magnitude (with a unit) and a direction to completely describe it. GENETIC. . ENGINEERING. Genetic engineering is the manipulation of genetic materials which can be introduced in the host organisms and thus change the phenotype of the host organism.. Matrices. Definition: A matrix is a rectangular array of numbers or symbolic elements. In many applications, the rows of a matrix will represent individuals cases (people, items, plants, animals,...) and columns will represent attributes or characteristics. Motivating Question. : An Airplane flies north with an airspeed of 575 mph. If the wind is blowing 30° north of east at 50 mph, what is the speed of the plane as measured from the ground? What if the wind blew south of west?. Quiz-. By: . Atul. . Soral. QUESTION 1. Displacement is a. A. Scalar quantity. B. Vector quantity. C. Base quantity. D. Derived . quantity. QUESTION 2. The adding of two vectors to get a single vector is termed as. Scalar quantities . have only a magnitude (amount).. Vector quantities . have a magnitude . and. a direction. . We represent them as . arrows. .. Distance. (d): the separation between . two points. . Any vector can be resized by multiplying it by a real number (scalar).. Multiplying by positive scalar changes magnitude only.. Multiplying by a negative scalar changes the magnitude and its direction..
