data Determination of the gravitational acceleration of the earth with great precision. Benefits: 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. Equipment and technical data: Release unit with ball Impact switch
