KEY KNOWLEDGE
Identify parameters of motion as vectors or scalars
OUTCOME
By the end of this lesson you will be able to use vectors to illustrate displacement from position vectors.
Adding Vectors
Adding Vectors
Vectors are added by pacing them head to tail and then drawing a resultant vector. Vectors are subtracted by adding the opposite or negative of the subtracted vector and then finding the resultant.
