Physics of Sports/Action
You will work in groups of 3. You must pick some aspect of a sport to cover. You will collect all the data
you can on that aspect, including video of the action being performed. All your data will be analyzed.
To Do:
1. Identify the sport or action you will investigate.
2. Capture the action on video.
3. Create a shared drive for your group.
4. Save the video in your shared drive.
5. Conduct analysis of motion of all important objects (i.e. bat and ball for a baseball swing). The
specifics will vary greatly by group. However, you should try to incorporate answers to the
following ideas:




Was there constant velocity? If so, when and how do you know?
What is the highest velocity you measured?
How did velocity change? Why does velocity change?
What about acceleration?
o Is there acceleration?
o Is it constant?
o Does area under your acceleration graph equal the change in velocity you read from your
data table?

What are the masses of your objects? Did you measure them or estimate them? If estimated how
did you arrive at your value?
What is the highest force you can find?
How does your video demonstrate Newtons Three Laws? How can you prove this?
What forces exist in your system? Draw a free body diagram for each of your objects.

Please do not simply give me a list of answers to questions. Make it paragraph text. You should include
graphs and or pictures to help support your conclusions.

There are opportunities for bonus points all along the way in this project. What counts as a bonus?



Going above and beyond what I've asked for. What does this mean? I'm not sure, but I'll know it
when I see it.
Collecting extra data along the way to add to your initial video. This may include, but is not limited
to:
o Shooting new video to highlight a specific aspect
o Using some of our Vernier Sensors to collect data
Adding an experimental question that you can test (will probably also necessitate collecting more
data)
