    Kinematics Physical motion is described by the variables:  position,  velocity and  acceleration. Let us first consider motion in one dimension  along a straight line We use the particle model A particle is a point-like object with mass but  possesses infinitesimal size

    Vectors and Scalars A vector quantity requires the  specification of both direction and  magnitude For 1D, use + and – signs to indicate  vector directions Scalar quantity has a numerical value  and no direction

    Displacement The displacement of a particle is defined as its  change in position in some time interval. As the particle moves from an initial position  x i  to a  final position  x f   , the displacement of the particle is  given by Displacement is a vector. Hence,
