Compound Measures and Real Life Graphs

1. Displacement (s)
   1. Distance in a given direction
   2. Metres (m)
   3. The straight line distance between two points
      1. Accompanied by the direction
2. Velocity (u or v)
   1. The rate of change of displacement with respect to time
   2. Average velocity = (u + v)/2
      1. U = initial velocity
      2. V = final velocity
3. Acceleration (a)
   1. Rate of change of velocity with respect to time
   2. Metres per second squared
   3. (change in velocity) / (time taken)
      1. (v - u)/ t
