- - - - Case 1: m constant, v changing
        F = ma
      - Case 2: v constant, mass changing
        F = v (dm/dt)
        e.g. helicopter thrust (air), rocket thrust (gas), stream of water
      - Case 3: m and v not constant
        Use 1st principle to solve
        (i.e. F = change in momentum / time taken)
    - - Draw FBD (always)
