  • Physics:2a
    • Distance- time graphs
      • gradient= speed
      • flat line- stopped moving
      • straight ( uphill/ downhill) line= steady speed
      • steeping curve= acceleration
    • Acceleration
      • how quickly velocity is changing
      • acceleration m/s^2= change in velocity(m/s)/ time(seconds)
    • speed and Velocity
      • speed and velocity tell you how fast you are going
        • velocity gives a direction but speed does not
        • speed= distance/ time
    • Velocity- time graphs
      • gradient= accceleration
      • flat line= steady speed
      • straight uphill line= acceleration
      • curve= change in acceleration
      • distance=area
