Download the free App Phyphox https://phyphox.org/download/ (Links to an external site.)
Prepare a file with pictures of your set up.
Include also a screen shot of the App PhyPhox with frequency and speed charts.
Include also the excel file with the raw data.
Here are for example, pictures
part 2
On the same report file include:
1) A couple of paragraphs of what you did. How did you set up the experiment. In particular, which adjustments did you have to do for the experiment to work best.
2) Paste the excel file chart with the cleaned data and describe the relation with the frequency and the changing speed. High frequency corresponds to which pendulum's velocity….positive or negative? Explain the shape of the frequency vs. time chart and of the speed vs. time chart.
3) From conservation of energy determine the speed the pendulum and compare it with the speed obtained from the App. Be careful to correctly report the height of the pendulum. It should be the height of the oscillation which is the height difference between the rest position of the pendulum and the height of the displaced pendulum. Delta h , not just how far the pendulum was from the floor when you started the oscillation! .
On your submission attach also the complete excel file with table and chart.
