We constructed a support to hold the tape time in the air (like the one above). We then ran a strip of paper through the time and attached a mass to it. We made sure that there was no slack in the paper, and that it could fall uninhibited to the floor. Then we started the tape timer and let the mass fall. Finally we measured the distance between the dots on the paper strip and recorded it in our data tables. Data: We used a ruler to measure the dots, and a ruler only measures to 1/10 of a cm (.1). We had to estimate to get the hundredth place. 1) Why would you have to remove the slack before letting the mass fall?
