Resultants





















Today we began the class with mental math, as usual. After, Mr. Max did a homework check on Exercise 2, question 8 and another question of our choice.


Resultant - the new vector created when two or more vectors are 'added.'

Adding Vectors
1) Triangle Method (makes a triangle; uses only two vectors or many vectors.) head to tail
2) Parallelogram Method (makes a parallelogram; only uses two vectors, when an angle between them is known.) tail to tail
