ABSTRACT:
A highly compact and portable free-fall apparatus for the absolute determination of the acceleration of gravity, which allows for rapid, convenient and precise measurements. The apparatus utilizes mercury as the falling mass and has design features that makes it possible to carry out experiments in vacuum or various gaseous environments under controllable conditions of temperature and pressure. The apparatus conveniently and automatically generates a large number of data in a relatively short period of time allowing for meaningful statistical analysis.
