Thursday, September 28

 

  • 2-D vector addition basics
  • Vectors heads and tails
  • Components and resultants
  • Trigonometry primer - using the Pythagorean Theorem and sin, cos, tan identities
  • Some 1-D and 2-D displacement examples

 

Friday, September 29

 

  • You walk 300 m west then walk 458 m at 70° N of E. Determine displacement
  • Vector A is 3.0 m east. Vector B is 5.0 m north. Find A+B, B+A, A–B, B–A, –A–B. Compare resultants in terms of commutitive property of addition and how vector sums may be similar or different in magnitude and or/direction.
  • You walk 250 m south then walk 400 m east then walk 100 m north. Usefulness of component addition chart.
