  1. Interpreting Motion Graphically A few basics to remember… • The slope of a position-time graph provides velocity information… • Steeper = faster motion (position chaging at a faster rate) • + slope = motion in the positive direction (positive value of velocity) • - slope = motion in the negative direction (negative value of velocity)

  2. Interpreting Motion Graphically • The slope of a velocity-time graph provides acceleration information… • Steeper = greater acceleration (velocity chaging at a faster rate) • + slope = acceleration in the positive direction (positive value of acceleration) ***Note: this does not always mean moving in the positive direction • - slope = acceleration in the negative direction (negative value of acceleration) ***Note: this does not always mean moving in the negative direction

  3. Not Moving: Position time Velocity time Acceleration time

  4. (+) direction, constant v Position time Velocity time Acceleration time

  5. (-) direction, constant v: Position time Velocity time Acceleration time

  6. (+) direction, increasing speed: Position time Velocity time Acceleration time

  7. (+) direction, slowing down: Position time Velocity time Acceleration time

  8. (-) direction, increasing speed: Position time Velocity time Acceleration time

  9. (-) direction, slowing down: Position time Velocity time Acceleration time
