Exam 1 friday sept 14th! (covers hw 1-3) To add (or subtract) vectors using components, first break up the original components into. To get the components of the new vector, add the components of the original vectors. To get the magnitude, us the pythagorean theorem. Displacement is a vector that points from the initial position to the final position. Velocity is the rate of change (in time) of your displacement. In 1 dimension, it is the slope displacement vs time plot. Speed is just the magnitude of velocity ( how fast , not which way ) absolute value of velocity into vectors lope of the absolute value of velocity.
