Vectors and Scalars AP physics B. Scalar Scalar Magnitude A SCALAR is ANY Example quantity in physics that Speed 20 m/s has MAGNITUDE, but NOT a direction associated with it. Distance 10 m Magnitude A numerical value with units. Age 15 years Heat 1000. calories vector A vector is ANY vector Magnitude quantity in physics that & Direction has BOTH Velocity 20 m/s, N. MAGNITUDE and DIRECTION. Acceleration 10 m/s/s, E. Force 5 N, West r r r r Vectors are typically illustrated by drawing an ARROW above the symbol. v , x, a, F The arrow is used to convey direction and magnitude. Applications of Vectors vector ADDITION If 2 similar Vectors point in the SAME. direction, add them. Example: A man walks meters east, then another 30. meters east. Calculate his displacement relative to where he started? m, E + 30 m, E Notice that the SIZE of the arrow conveys MAGNITUDE and the m, E way it was drawn conveys DIRECTION.
