Oaks Park Analysis

Before Oaks Park:

1. Download the Sensor Kinetics Pro app.
2. Watch this video:

3. Practice using the app.  I really like the "Low Pass" filter on the Accelerometer.
4. Carefully read the all directions on the lab handout.
5. Make a data table and a checklist for your group to use at the park so you don't forget anything. 

After Oaks Park:

Help with your Vertical Circle ride: 

For your vertical circle ride, you are going to use Physics formulas to calculate the centripetal acceleration.  The radii of the rides you can find on the Oaks Park Data site (Link at the top of this page).  To find the periods for the rides that go in a circle, you can look at your accelerometer data and use cleverness.  Once you have the centripetal acceleration, you will need to be able to compare that intelligently to the accelerometer data you collected.

Overview of a Vertical Circle ride:

2. Using Graphical Analysis on your Chromebook

3. Calculating your centripetal acceleration: (Ferris Wheel/Rock-O-Plane/Zero-G)
Finding the period from your data:
3. Calculating your centripetal acceleration: (Scream-N-Eagle)

4. Predicting and Comparing what your accelerations should be (Zero-G)

Help with your Linear Acceleration ride:

For your linear acceleration ride, you are going to use Video Analysis in LoggerPro (On a PC or a Mac at school, or there is a way to install it at home - ask me) to measure the acceleration of the ride.  You then need to be able to intelligently compare the accelerometer data to the calculated accelerations from LoggerPro.

Overview of a Linear Acceleration Ride:

1. Getting your video from your phone to a PC or a Mac using the Google Drive App:
2. Doing video analysis to find acceleration (Frog Hopper/Drop Tower)

3. Getting your SKP data from your phone to Graphical Analysis on the Chromebook
4. Comparing video analysis to Accelerometer data: (Frog Hopper/Drop Tower/Spider)

Help with your Energy ride:

For your Energy ride, you are going to take pictures of the energy ride, and use LoggerPro to find the elevations of the ride at three different points.  We know their initial height from which the ride starts, and we then use conservation of energy formulas to calculate what the velocities should be at the different elevations you found.  Finally you can use LoggerPro to measure the speed of the ride at those different  elevations.  Then you will need to intelligently compare the calculated velocities to the actual measured velocities.

You don't have to ride the ride or measure the acceleration of the ride to do this.  Adrenaline Peak is really the better ride to choose, in my opinion.

Overview of an Energy Ride:

1. Getting your pictures from your phone to a PC or a Mac
Just email them to yourself as attachments, and log onto your email on a PC or mac in the room, and download them.  You might want to rename them so you can find them.  If you use Chrome, click the down arrow to the right of the download in the tray, and click "Show in Folder" and then move it or rename it.
Here are some fine pictures from the web you could use for Adrenaline Peak:

5. Using video analysis on a PC or Mac to determine the actual velocity (Adrenaline Peak)

6. Comparing the calculated velocity to the actual velocity
Yup - just say what they both are.  Remember, our calculations do not take into account friction.  Adrenaline Peak probably has a medium to small amount of friction, but the big pink slide has a ton of friction.  Your predicted velocities will be nowhere near the actual velocities.
