Introduction to Vectors John Weisenfeld EDU6170, Summer 2011
Introduction • Definition: • Scalar • Vector • Notation: , or just v is ambiguous, hard to differentiate bold/non-bold in notes. • Representation: • Arrow shows direction • Length is magnitude • Can also do in 3D, not just 2D.
Question Zero
Which Vector has Positive X-Component and Negative Y-Component Green (b) Blue (a) Neither
Which Vector has a Magnitude of 5? Green (b) Blue (a) Neither
C O N G R A T U L A T I O N S • You now have a basic understanding of vectors!
Closure / Summary • Today we have learned • Vectors have direction and magnitude. • They can be added in 3 ways • Tip-to-tail • Parallelogram • Component method • These components are very useful. • Before the quiz this week • Give me the top sheet of your handout • Follow the instructions to ExploreLearning and take the quiz up there.
