| 'g' By FREE FALL APPARATUS, MECHANICAL RELEASE
(0129) |
| An excellent apparatus for determining the value of acceleration due to gravity 'g' to a better accuracy. The specially designed release mechanism permits use of spheres of different material [magnetic or non-magnetic) and sizes. Pulling the release pin of the sphere at the top breaks the continuity of wires connecting the release plate to the timer, starting the timing process, which is stopped immediately when sphere strikes the bottom plate. Height of release plate and bottom strike plate are adjustable. The complete assembly mounted on aluminium extrusion with a scale 0-100cm graduated in millimeters. By knowing the distance between the release plate and lower striking plate, and the time of fall, the value of 'g' can be easily evaluated. |
