Resumo de Recurso

Motion
  1. Distance-Time Graphs
    1. Gradient of line = SPEED
      1. For an object at a constant speed: SPEED=DISTANCE TRAVELLED/TIME TAKEN.
        1. Unit of speed is metre/second
          1. Reading the graph
            1. stationary=horizontal line
              1. accelerating/decelerating=curve
                1. constant speed=diagonal line
              2. Velocity and acceleration
                1. velocity=speed in a given direction
                  1. acceleration=change of velocity per second.
                    1. unit is the m/s2
                    2. acceleration=change in velocity/time taken
                    3. velocity/time graphs
                      1. horizontal line=constant speed
                        1. gradient=acceleration
                          1. area under line=distance travelled
