Rút ngắn thời gian tiến hành thí nghiệm xác định gia tốc trọng trường bằng con lắc thuận nghịch
Abstract: The experiment to determine the acceleration of gravity by a reversible pendulum is a common set of experiments in laboratories in educational institutions. It is a simple, affordable, and highly accurate test kit. However, which This experiment has the limitation that the time to complete the experiment is long, the accuracy depends alot on the manipulation of measuring and processing results of the experimenter. We have come up with a solution to shorten the time to perform the experiment in half while still ensuring the accuracy of the results.56
