Item A comparison of gravitational acceleration measurement methods for undergraduate experiment(Institute of Physics Publishing, 2018) N. Suwanpayak; S. Sutthiyan; K. Kulsirirat; P. Srisongkram; C. Teeka; P. Buranasiri; N. Suwanpayak; Department of General Science, King Mongkut's Institute of Technology Ladkrabang, Prince of Chumphon Campus, Chumphon, Thailand; email: ksnathap@gmail.comThis research aimed to determine the acceleration due to gravity (g), by using the methods of free fall, simple pendulum, physical pendulum and an Atwood's machine in the undergraduate laboratory. The experiments were designed for students to explore, analyze the data and interpreting the results by using the principle of a Physics laboratory. The mean experimental values of acceleration due to the gravity of free fall, simple pendulum, physical pendulum and the Atwood's machine were 9.64 m/s 2 , 9.67 m/s 2 , 10.88 m/s 2 and 10.47 m/s 2 , respectively. � Published under licence by IOP Publishing Ltd.
