Chapter 2    Kinematics in one dimension

Concepts:  Displacement, 

                Average and instantaneous velocities (rate of change of displacement)

                Acceleration (rate of change of velocity),

                Speed (scalar),  velocity (vector)

 Constant acceleration- Equations relating x, v, v_o, a and t

                                    v = v_o + at

                                    x = (v_o + v)t/2

                                    x =  v_ot + at²/2

                                    v² = v_o² + 2ax

Bodies under free fall-  constant downward acceleration of 9.8 m/s² or 32 ft/s²

Interpreting displacement-time graphs,  and velocity-time graphs
