Motion Along a Straight Line (Physics)

Recall cards on one-dimensional kinematics: position and frame of reference; displacement as the change in position (final minus initial), a vector measured in meters, and its distinction from distance traveled; average velocity as displacement over elapsed time; instantaneous velocity as the time derivative of position and the slope of a position-versus-time graph; speed as a scalar and instantaneous speed as the magnitude of velocity; average and instantaneous acceleration as the rate of change of velocity and the slope of a velocity-versus-time graph, with the sign conventions relating acceleration and velocity direction to speeding up or slowing down; the constant-acceleration kinematic equations and the notation behind them; free fall under gravity alone with acceleration g directed downward; and finding velocity and displacement by integrating acceleration and velocity over time.
