PPT-Force Vectors

Vectors Have both a magnitude and direction Examples Position force moment Vector Quantities Vector Notation Handwritten notation usually includes an arrow such as Vectors are given a variable such as A or B. 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 Vojin .

In some cases, we will have to decompose a vector into a sum of two separate vectors. Recall; most vectors may be written as some variation of the special unit vectors {1,0} and {0,1}. With vectors, sometimes they may not be pointing or oriented in the proper direction. Chapter 2. The stuff you should know:. Laws of Motion. Finding resultant forces. In 2D. Non-orthogonal axes. Law of Sines, Law of Cosines, Parallelogram law, Head to Tail Addition. Orthogonal. Add Cartesian Vectors(especially if more than 3 forces). 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. WARM UP: Get Out Homework Describe the difference between constant velocity and acceleration. Give a detailed example of each. I Think I can, I think I can, I Think I can! - I can explain the relationship between acceleration, force, and mass. Examples should include: . velocity/speed, mass, force/weight, acceleration, displacement/distance. . Addition of vectors by calculation or scale drawing. . Calculations will be limited to two vectors at right angles. Scale drawings may involve vectors at angles other than .
