Atwood S Machine Lab Report

NEWTON’S SECOND LAW: ATWOOD MACHINE Introduction One may study Newton’s second law using a device known as Atwood’s machine, shown below. It consists of a pulley and two hanging masses. The difference in weight between the two hanging masses determines the net force acting on the system. This net force accelerates both of the hanging masses; the heavier mass is accelerated downward and the lighter mass is accelerated upward. This system is convenient for studying motion under constant acceleration...
