  1. 1. Kinematics Topic 2.1 2.1.7 – Draw and analyse distance – time graphs, displacement – time graphs, velocity – time graphs and acceleration – time graphs. 2.1.8 – Calculate and interpret the gradients of displacement – time graphs and velocity – time graphs, and the areas under velocity – time graphs and acceleration – time graphs.
  2. 2. Distance– time graphs
  3. 3. Displacement – time graphs
  4. 4. Graph info <ul><li>Increasing slope means increasing velocity </li></ul><ul><li>Constant slope means constant velocity </li></ul><ul><li>Decreasing slope means decreasing velocity </li></ul><ul><li>Horizontal point (zero slope) means zero velocity </li></ul><ul><li>Negative slope indicates negative velocity </li></ul><ul><li>Flattening curve implies velocity becoming less negative </li></ul><ul><li>Continuing zero slope implies the object is at rest </li></ul>
  5. 5. Velocity – time graphs
  6. 6. Velocity – time graphs
  7. 7. Graph info <ul><li>Positive slope means positive acceleration </li></ul><ul><li>Horizontal line (zero slope) means zero acceleration </li></ul><ul><li>Negative slope means negative acceleration </li></ul>
  8. 8. Acceleration – time graphs
