Lab Manual Errata – Week 6 7.1 p. 65 In addition to Equation (7.1), Hooke's law is also written as F spring = -k Δ x , where F spring is the force exerted by the spring on an object attached to it. 7.2 p. 66 Step 2 – Do not weigh the masses until after you have put the tape on them. p. 66 Step 3 – Do not tape or clip the spring to the hook unless necessary. Make sure the ruler is oriented so that the readings increase downward toward the ground. p. 66 Step 4 – If you are using the toughest springs, use 20 g increments, taking a total of 10 measurements, but do not add more than 200 g to the mass holder. After incrementing the mass load to the maximum, decrement the load going back down using the same mass combinations and record this data as well. Now you should have 20 data points plus the equilibrium point. As a tip for sharing weights, note that if you have five masses that measure 10 g, 20 g, 20 g, 50 g, and 100 g, you can combine them to make 20 g, 40 g, 60 g, …, 200 g. p. 66
