Day 2: The experiment begins

By -
Project Name: BCC G Project
Time: 1pm to 3 pm

Today, we started with the initial trials for the new free-fall experiment setting up the experiment apparatus and shooting the video through different cell phone cameras. First off, we collected a few items that can be dropped from a height slightly higher than 2 meters. We found a golf ball, a wooden ball and a small steel ball. In figure 1, you can see the slow motion video of the first trial taken using iPhone 7 with 720p and 240fps of the golf ball dropped from above the door height. Figure 2 shows the second trial taken using Samsung Galaxy S7 Edge with the same quality. We thought it was important to try taking the slow-motion video in different cell-phones because we were checking to see if it was feasible for students to take their own videos in class to perform the experiment. Now, we're going to try to use different apps and software such as PASCO that will allow the students to analyze the video and find measurements and other information for the calculations.

Day 40: Analyzing Conservation of Momentum videos

By -
At 1 pm, the team attended the 3SP meeting today. After returning to the office an hour later, the team began to analyze the videos for the Conservation of Linear Momentum experiment recorded last Monday, July 23rd. Since the free software trial expired on both member's personal computer, they set up the software on mentor Dr. Epstein's office computer. They were able to analyze one of the slow-motion videos of the colliding gliders. It was confirmed that using the software is indeed a better way to produce the expected results. As claimed, the initial velocity of glider 1 was approximately equivalent to the final velocity of glider 2 after the collision:    Pᵢ = P f         (initial momentum = final momentum) ∴   m v ᵢ = m v f   ∴ v ᵢ =  v f          (when masses of both the gliders are equivalent) Meanwhile, progress is being made on the presentation for 3SP meeting on Thursday. It is almost done,...

Day 15: Drag Calculation + Progress on Manual

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...

Day 7: Microsoft Excel

The last videos were analyzed using PASCO Capstone. We notice inconsistence in g values for different masses. Thus, we plan to study the results for particular masses by performing additional trials on Monday. Image 1 displays a screenshot of a table in Excel. The table mentions the object's (ball's) type including lead, steel, golf, wood, and hollow plastic toy ball corresponding to it's experimental gravitational acceleration value.  Image 1 . Screenshot of Excel Table The first graph, Figure 1, was created using Microsoft Excel. It displays data with the relationship between gravitational acceleration and mass of lead, steel, wood, golf, and hollow plastic toy ball.  Figure 1. Gravitational Acceleration vs Mass of Various Balls. As described in yesterday's blog, we measured the effect of dropping the ball not even with the meter stick. Figure 2 presents the second graph created on Microsoft Excel. Our data for the steel ball is exhibited below. Neg...
