1 Adding Vectors at Right Angles Instructor: Ms. Chase

2 Are You Prepared? Reference tables http://www.ncpublicschools.org/docs/ accountability/testing/eoc/Physics/phy sicsreferencetable.pdf http://www.ncpublicschools.org/docs/ accountability/testing/eoc/Physics/phy sicsreferencetable.pdf Pencil Paper Online calculator (if needed) http://www.ecalc.com/ http://www.ecalc.com/

3 If vectors are at right angles (90  ) –move the vectors and place them head to tail –draw resultant from tail of the first to head of the last –use Pythagorean theorem to find resultant –use tan  = opposite/adjacent to find direction

4 Demonstration Vector addition at right angles is similar to finding the displacement: http://www.youtube.com/watch?v=gVujFPpiL G0

5 Practice Let’s do some practice problems…

6 Homework Print off the “Vectors at right angles” worksheet, complete and bring with you to the next lesson.

7 Physics is fun!
