描述
English: acceleration of Saturn V during Apollo 8 launch
. The marked events in the graph are:
  1. Launch with ignition of the S-IC. Note how the acceleration rapidly rises with increasing engine efficiency and reduced propellant load.
  2. Cut-off of the centre engine of the S-IC.
  3. Outboard engine cut-off of the S-IC at a peak of 4g.
  4. S-II stage ignition. Note the reduced angle of the graph for although the mass of the first stage has been discarded, the thrust of the S-II stage is nearly one tenth of the final S-IC thrust.
  5. Cut-off of the centre engine of the S-II.
  6. Outboard engine cut-off of the S-II at a peak of approximately 1.8g.
  7. S-IVB stage ignition. Note again the reduced angle of the graph caused by the thrust being cut to a fifth.
  8. With the cut-off of the S-IVB's first burn, the vehicle is in orbit with zero acceleration.
