EXPERIMENT 3: NEWTON'S SECOND LAW AND THE ATWOOD MACHINE Materials A computer simulation, excel, calculator. Part A: Atwood's Machine Virtual Lab In this activity, you will be using a simple assembly named the Atwood machine that is like that used by Rev. George Atwood in 1784 to verify Newton's Second Law. This virtual lab show the relationships between acceleration and total mass and acceleration and net mass (net force) using an Atwood Machine simulation . Part BConstant total mass with increase the mass difference (or net force) How is acceleration affected by an increase in net mass? My initial hypothesis, to answer this research question is (check one) is: _____ If the net mass of the system is increased, then the acceleration increases. _____ If the net mass of the system is increased, then the acceleration decreases. _____ If the net mass of the system is increased, then the acceleration is not affected. Table B: Comparison of acceleration versus increasing net mass difference
