Consider Atwood's machine with two masses, m_{1}and m_{2}with m_{1}less than m_{2}. Now, according to application of Newton's third law, the system accelerates in the direction of the heavier mass (here, m_{2}). This, however, seems to contradict Newton's third law, which implies that the interaction between the block and the rope are equal and opposite. That is, the tension of the string should counteract the force of gravity on each block. Obviously, though, there is a fallacy someplace in my argument. Does anyone mind pointing it out?
