  • P1
    • Force (newtons, N)
      • Gravitational Potential Energy
      • Power = work/time
      • Resistive forces include air resistance, friction, brakes
        • Balanced forces
          • constant speed
          • terminal velocity
      • resultant force
        • acceleration (meters per second2)
          • W = m x g
          • time (seconds, s)
            • Velocity-time graph
              • acceleration (meters per second2)
                • W = m x g

                    • speed (meters per second)
                      • cameras
                      • velocity = speed + direction
                        • momentum     p = m x v
                          • safety features reduce momentum gradually
                          • momentum is conserved in collisions
                    • distance-time graph
              • speed (meters per second)
                • cameras
                • velocity = speed + direction

              • distance-time graph
          • springs
            • extension  proportional to force
              • F= k x e
            • elastic potential energy
      • distance (meters, m)
        • work done = energy transferred
          • kinetic energy
            • regenerative breaking uses kinetic energy to recharge battery
            • bakes convert kinetic energy to heat
        • stopping distance = thinking distance + braking distance
          • poor road and vehicle conditions increase braking distance
          • bakes convert kinetic energy to heat
