vector addition 

Summary

When more than one vector affects an object, you don’t look at them separately you add them to find the net (resultant) vector if vectors are in the same line, you can add or subtract them using positive and negative signs if they are at angles, you use drawings or math methods like tip to tail or the Pythagorean theorem to find the final result

• Net vector = total result of all vectors

  Collinear vector:

• Same line

• Add/subtract with + and + signs

  Non-collinear vector:

• Different directions

• Need drawing or trig

  Tip to tail method

• Draw vectors head to tail

• Net vector goes from start to end

  Pythagorean method

• Only for right angles

  Trig method

• Works for any angle
