Apparatus:We used iron rods and clamps to give us a foundation for our meter stick and our clay to stand on. Next we got a rotary sensor and attached it to the rod using clamps. This sensor was not actually used to obtain data. It was only used since it gave us a good post to slide in our meter stick which allowed it to rotate. We Then grabbed a computer and plugged in a camera to obtain a video capture.
Our Set Up
What we did. First we weighed the meter stick. Then we crimped down our meter stick with the gasket onto the iron rod.. Next we got a piece of clay, wrapped it around a piece of tape and weighed it. Next we made a prediction of how high it would elevate.
Our Calcuations Say H=.108
After making our prediction we had to see how high it actually went. We Placed the clay on the bottom rod, lifted our meter stick to make it horizontal to the floor, we pressed video capture, and finally we let go of our meter stick. The camera took video of the whole rotation
.Next we opened up our video on logger pro. First we set an axis on our video which was where the collision took place and horizontal to the floor. Next we scaled our video so it could get a measurement of how high it went. After we clicked plot and followed the movement as it hit the clay all the way to the peak height. This last dot gave us the final height.
Conclusion: We were able to predict the height the meter stick would travel using the formulas above. Our prediction was that it would travel .108 meters high. Logger pro stated that it traveled .08 meters high. Our prediction was off by 2.8 cm which is significantly close to the actual. Things that may have caused this uncertainty may be friction,.
