  • -Time Graphs
    • Distance-Time Graphs
      • GRADIENT = SPEED
      • Flat = Stationary
      • Straight UP or DOWN hill = steady speed
      • Steeper = faster
      • CURVES = ACCELERATION or DECELERATION
      • DOWNHILL = back to start point
      • Steepening curve = speeding up
      • Leveling off curve = slowing down
      • SPEED = the GRADIENT = Y axis / X axis
        • (Distance / Time)
    • Velocity-Time Graphs
      • Flat = steady speed
      • Steeper = greater acceleration or deceleration
      • UPHILL = ACCELERATION
      • DOWNHILL = DECELERATION
      • AREA under section of graph = distance travelled
      • Curve = changing acceleration
      • GRADIENT = ACCELERATION (m/s squared)
        • ACCELERATION = CHANGE IN VELOCITY / TIME TAKEN
          • V             A X T
          • Acceleration = how quickly the velocity is CHANGING
            • CHANGE IN  SPEED
              • or BOTH
            • CHANGE IN DIRECTION
              • Untitled
          • (Y axis / X axis)
    • Distance  Speed X Time
    • Speed (m/s) = how fast your going
    • Velocity (m/s) = speed with DIRECTION
