  • Motion
    • Distance-Time graphs
      • Stationary-horizontal straight line
      • Moving at a constant speed - straight line at a gradient
      • Gradient of line represents speed
      • Speed in m/s = distance travelled (m) / time taken (s)
    • Velocity & accelleration
      • Velocity is speed in a given direction
      • Acceleration is change in velocity per second. (m/s^2)
      • Acceleration = change in velocity / time taken
      • Deceleration is change in velocity when an object slows down
    • Velocity-time graphs
      • Horizontal line = 0 acceleration
      • Gradient is the acceleration
      • Area under line is the distance travelled
