g--Acceleration of Gravity: Its Measurement from the Shape of Water by Using a Computerized Rotational System
Pintao, Carlos A. F.; de Souza Filho, Moacir P.
European Journal of Physics, v28 n5 p915-921 Sep 2007
This paper proposes a different experimental setup compared with the traditional ones, in order to determine the acceleration of gravity, which is carried out by using a fluid at a constant rotation. A computerized rotational system--by using a data acquisition system with specific software, a power amplifier and a rotary motion sensor--is employed in order to evaluate the angular velocity and g. An equation to determine g is inferred from fluid mechanics. For this purpose, the fluid's parabolic shape inside a cylindrical receptacle is considered using a rotational movement.
