The two kinds of motion most commonly considered are rectilinear motion and curvilinear motion. ____ the term implies, rectilinear motion ____ a particle is motion along a straight line. Curvilinear motion is motion ____ a curved path. If a particle has rectilinear motion ____ respect to some point ____ is assumed to be fixed, its displacement is its total change of position ____ any given interval of time. Displacement is independent of the path traversed and depends only ____ the initial ____ final position of the particle. It is a vector quantity and is represented graphically ____ a vector.
