1. 2D Motion – an algebraic approach

2. Get yer brains ready!

3. Adding vectors
From yesterday we know that adding vectors that are perpendicular is relatively straightforward.
Adding non-perpendicular vectors algebraically involves breaking them down into perpendicular parts.

5. This is NOT a scale diagram
This is NOT a scale diagram! We have only shown the magnitudes in the diagram.

6. Find the Magnitude and direction

7. This handy dandy flow chart might help some people

8. What if the vectors aren’t perpendicular???

10. How can we find the magnitudes?

11. We can add displacement vectors by components!
DO THIS WHEN: One vector has a direction DUE north, south, east, or west

13. What if neither vector has a direction due north, south, east, or west?

16. Now for Velocity!
Adding Velocities in Two Dimensions

17. Example 1 – No Current

18. Example 2 – with current!
Current = 24 km/h [E]
