Alta High Conceptual Physics Vectors and Scalars Vector vs. Scalars Vectors have both magnitude and direction Displacement, Velocity, Acceleration, Force,  and Momentum Scalars have only magnitude Mass, Time, and Temperature
Alta High Conceptual Physics Vector Addition Two Methods Graphical Method Requires a ruler and a protractor Process Convert each vector into a line that fits a scale of  your choosing Draw Vectors head to tail, measuring the angle  exactly Draw a resultant Measure the resultant and the resulting angle Convert the measurement back into a vector answer

Alta High Conceptual Physics Graphical Addition A man drives 125 km west and then turns  45º North of West and travels an additional  100 km.  What is his displacement? Step one: Set Scale 1 cm = 25 Km 125 km = 5 cm 100 km = 4 cm 45 °
Alta High Conceptual Physics Graphical Addition Step Two: Move Vectors Head to Tail Step Three:  Draw Resultant from Tail of First  Vector to the head of the last. 125 km = 5 cm 100 km = 4 cm 45 °
