27 Analysis I

At this point, you should have two good sets of data for each ball that are relatively smooth for the position, velocity, and energy graphs (before and during the fall). For each ball:

1.  Select the best of the two data sets you collected for that ball.

2.  Identify the point at which the ball begins to fall and delete all of the data before it.

3.  Click the Scale-to-Fit icon on the graph toolbar (very left side).

4.  Once you have selected your three graphs and they are presentable, ask your TA to check them. Add these graphs to your report and make sure they are properly labeled and titled. 

 

CHECKPOINT

(Ask the T.A. to check your best plots for the three balls)

 

Copy the position, velocity, and energy versus time graphs, and paste them into your report. You can copy and paste these graphs simply by:

1.  left clicking the highlighted region around your graphs in Capstone,

2.  pressing ctrl+c to copy the graph,

3.  pressing ctrl+v in your word document to paste the graphs into your report.

 

Question 4.

Based on the discussion of isolated systems in the Theory section, does your data justify treating each falling ball as an isolated system within this experiment? Compare and contrast between the different balls used. Which type of graph (position, velocity or energy versus time) justifies your answer the best and why?

 

Question 5.

Based on your results, which of the three balls is affected the most by the drag force from air resistance? How does the geometry and material of the balls affect the drag force? Hint: Consider Equation (5) in your arguments.
