The first step in this lab was to weigh the mass of each pipe using the scale. We then wrote down the weight (kg) of each pipe on our data sheet and measured the radius ( in terms of meter) of pipe. Next, we hypothesized which of the pipes would roll down the first and reasoned why. After finishing up with our hypothesis, we calculate each pipes I value with the formulas I = ½(mr2) for solid cylinder & I = mr2 for ring. Now we can set up for the experiment by creating a ramp by stacking the textbooks and leaning the wooden board against the textbooks. Then measure the distance, height, and slope. Finally roll each pipe down the ramp individually and record the time it takes to reach the end point. Repeat this process three times for each
