PPT-Units, scalars and vectors

Physical quantities Any quantity that can be quantified by measurement is a physical quantity Most of the quantities we deal with as scientists are physical quantities and they will be the ones we will discuss throughout this topic of motion. 1 Motivation A3 A2 Vectors A3 A21 Notational Conventions A4 A22 Visualization A5 A23 Special Vectors A5 A3 Vector Operations A5 A31 Transposition A6 A32 Equality A6 A33 Addition and Subtraction 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 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. . Objectives. :. Distinguish between vector and scalar quantities. Add vectors graphically. Scalar. – a quantity that can be completely described by a number (called its magnitude) and a unit.. Ex: length, temperature, and volume. 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. . Scalar. A . SCALAR. is ANY quantity in physics that has . MAGNITUDE. , but NOT a direction associated with it.. Magnitude. – A numerical value with units.. Scalar Example. Magnitude. Speed. 20 m/s. John . Cadigan. , David Ellison, Ethan Roday. System Overview. Document summarization system is organized as a multi-step pipeline.. System Overview. Two major components for content selection:. Feature selection step to generate sentence vectors. Vectors, Shmectors. Objectives. 1. Distinguish between a scalar and a vector.. 2. Add and subtract vectors by using the graphical method.. 3. Multiply and divide vectors by scalars.. Vectors, Schmectors. 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.. 1. Changing Units. Speed of a car is 80 miles/hour. What is it in m/s. Multiply by 1 so units cancel and correct units are left. In units of m/s: {80 miles * (5280 feet/mile)*(1 m/3.28 feet)}/hour. &. VECTOR BORNE DISEASES. VECTOR. FIGHT. Version November 2017. About the Event:. By . KfW. Development during World Health Summit 2017. 15th. -. 17th October 2017 in Berlin. 20 ideas at the start – 8 ideas selected. In physics, we are often concerned with the direction of an object's motions. To represent direction we need to use vectors. "John was traveling at a of 100km/h" compared to "John was traveling at
