Day 31: Continuing from Thursday

The team picked up from where they left last week. While one of the members continued analyzing the recorded videos from last week, the other worked on finishing the lab manual revisions after the second practice trials. Moving forward, the plan is to gather some physics professors to try out the experiment to receive more feedbacks for the final testing. Over the weekend, Jan Mark 3-D printed a sample of the phone holder. Materials bought last week have been delivered. What's more, the members finished analyzing all the videos and created a chart to compare the values and determined the average gravitational acceleration of all the different angles. As you see from the screenshot above, the average gravity value (the slope) was determined to be 9.83 m/s² which is relatively close to the accepted value.

Day 15:  Drag Calculation + Progress on Manual After watching (and for Jan Mark, participating in) the afternoon presentations, we worked on 2 projects.  We are nearly done editing the experimental procedure section of our lab manual write-up of the Free-Fall experiment.  The complete write-up should be ready by early next week so that we can get volunteers to try the experiment. We were also able to use the ping pong ball data to calculate the drag coefficient, C, for a ping pong ball. Ping Pong ball data When air resistance is taken into account, the equation for acceleration of a falling body becomes: where ρ air is the density of air, A is the cross sectional area of the falling object and v is its instantaneous velocity. By plotting a vs the velocity squared, C can be derived from the slope. For typical falling objects, the range of C values is from 0.4 to 1. This graph is seen (will be inserted) below and the calculations give: Givin...
