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.
