  1. Introduction to Vectors John Weisenfeld EDU6170, Summer 2011

  2. 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.

  3. Question

  4. How did you get there?

  5. Question

  6. Tip-To-Tail,Commutative Property

  7. Question Zero

  8. Superimposing Coordinate Grid

  9. Which Vector has Positive X-Component and Negative Y-Component Green (b) Blue (a) Neither

  10. Which Vector has a Magnitude of 5? Green (b) Blue (a) Neither

  11. C O N G R A T U L A T I O N S • You now have a basic understanding of vectors!

  12. 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.
