Day 17: Reviewing the Manual

By -
The team continued finishing the write up for the manual and began reviewing it today. The plan is to have a few volunteer students test the experiment tomorrow to check whether the instructions are written clearly. Originally, the main objective of the experiment was to determine g experimentally and check its dependence on mass. However, after calculating the drag coefficient of the falling ping-pong ball two days ago, the team realized that including these calculations in the actual experiment would be a good idea so that the students can truly see the effect of air resistance on the experimental g . Therefore, the instructions for the drag coefficient calculations were added to the experimental procedure today.

Day 36: Working on the Presentation and Poster

By -

Today, the team started working on the presentation and poster. This includes creating an outline on what we have to talk about. A rough outline is listed below: Introduction  Recap Changes in the procedures and equipment What we need to do next Introduction of the future projects From there, the team started to design the power-point presentation. We are using the previous presentation done on Summer I as reference material to keep the design consistent. A preview is shown below: Figure 1: Presentation Preview For the poster, we ideally want to include a photo of the old experiment and our new experiment to showcase the differences between them. An estimated cost comparison between old and new experiments (such as equipment used) should also be implemented in the poster design.

Day 27: Air Track Trials and Plate for Friction Experiment

By -

Today we started by taking more trials for the air track experiment to find its repeat-ability and to refine some of the procedures we did on the first set of trials. These include adjusting the track to be parallel with the camera and also adding a sign to indicate which trial we were testing. From these trials we got the data shown below: Figure 1: Trials Using Stopwatches We also took videos for all the trials and will compare the calculated g value from both methods. We expect that the method using Pasco Capstone will result in a more accurate value for g. As shown with one of the previous trials, the value of g found from Pasco Capstone was exactly at -9.81 but this may just be a fluke, therefore, it is necessary to do more trials. The group also worked with Professor Balzarette to help create new surface plates for the friction track. These new plates will hopefully be much more serviceable than what is currently used (the metal track surface itself) and will be easi...
