Summary of Important Quantities, Equations and Concepts + Table 3.1: Summary of the symbols and units of the quantities used in Vectors Quantity Symbol S.I. Units Direction Displacement m yes Velocity m.s−1 yes Distance d m - Speed v m.s−1 - Acceleration m.s−2 yes Vector: A vector is a measurement which has both magnitude and direction. Displacement: Displacement is a vector with direction pointing from some initial (starting) point to some final (end) point and whose magnitude is the straight-line distance from the starting point to the final point. Distance: The distance traveled is the length of your actual path. Velocity: Velocity is the rate of change of displacement with respect to time. Acceleration: Acceleration is the rate of change of velocity with respect to time. Resultant: The resultant of a number of vectors is the single vector whose effect is the same as the individual vectors acting together
