Piece of flexible cardboard Stack of books to hold ramp in place at the upper end Sticky tape Meter stick Stopwatch Method: To set up the experiment, we stacked three books onto one end of the table. One end of the ramp was put with its flap in-between two books. The other end was taped down to the table. A few inches in front of the end of the ramp, we taped our d i marker. Then a few inches before the end of the table, we taped our d f marker. Directly below the edge of the end of the table, we lay our meter stick out in front of the table parallel to it. To time the marble, we set it at the top of the ramp and waited until it rolled onto the d i tape marker to push start on the stopwatch. Then we waited until it rolled onto the d

Unformatted text preview: f tape marker to push stop. The resulting time on the stopwatch was the time it took the marble to travel that distance between d i and d f . To determine R, we first set up the meter stick directly the edge of the table end. Then, one partner rolled the marble down the ramp while the other waited by the meter stick to see where the marble landed. That partner would then mark that point with table and line the tape up with the meter stick to measure the distance. That measured distance would be R. Data: Height of ramp= 9.41 cm Height of table=73.45 cm Distance between markers=66.21 cm Times and Distances Trial Time(s) Deviation(s) 1 .66 .03 2 .59 .04 3 .66 .03 4 .66 .03 5 .60 .03 Means: .63 .03 %: 5% Testing the Prediction Trial Measured Range(m) Deviation(m) 1 .4502 .0002 2 .4467 .0033 3 .4435 .0065 4 .4447 .0053 5 .4651 .0151 Means: .4500 .0061 %: 1.4%...
