Position is an example of a vector quantity. A scalar is a quantity with no direction. The mass of an object is an example of a scalar quantity.

MFMcGraw-PHY 1401 Chapter 3b - Revised: 6/7/2010 5 To add vectors graphically they must be placed “tip to tail”. The result (F 1 + F 2 ) points from the tail of the first vector to the tip of the second vector. This is sometimes called the resultant vector R F 1 F 2 R Graphical Addition of VectorsRead More
