Function and technical data

Determination of the gravitational acceleration of the earth with great precision.


  • The exclusively mechanical retention of the falling body allows to avoid mistakes caused by residual magnetism from electromagnetic retention systems for precision measurements of the falling times of a free falling ball.
  • Release unit with ball for timely defined local release of suited bodies, e.g. balls, falling rods,etc.
  • Impact switch release and impacts witch are fixed to a support by means of clamps.
  • This allows to determine the falling trajectory arbitrarily.
