Pintao, Carlos A. F.; de Souza Filho, Moacir P. – European Journal of Physics, 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…
