Equilibrium and Pulleys: Mass and Breaking Strings June 22, 2009 Purpose In this experiment, students will distinguish between inertia and force. Hypothesis When pulled fast, the lower string breaks because it cannot move the 2 kg mass  downwards as fast as the downward extension of the string. Thus, something must  "give", in this case the string. However, when pulled slowly, the 2 kg mass is pulled about  as fast as the lower string is being pulled, but the top string is being critically extended. Materials -1 kg mass -thread -base and stand Procedure 1) Two threads were attached to the top and bottom of the 1 kg mass. 2) One piece of thread was used to suspend the mass from a suitable support such as  a hook. The thread was barely strong enough to support the object when  suspended. 3)
