Resumen de A Measurement of gUsing Alexanders Diving Bell

M. E. Quiroga, S. Martínez, S. Otranto

• This paper describes a very simple exercise using an inverted test tube pushed straight down into a column of water to determine the freefall acceleration g. The exercise employs the ideal gas law and only involves the measurement of the displacement of the bottom of the �diving bell� and the water level inside the tube with respect to the water column surface. The experiment is ideal for students in introductory physics courses.
