Each student must submit a Data Record on this form to his/her physics instructor by 5:00 PM of the day following his/her State Fair visit. In writing your final report, you will only be allowed to use data given on this sheet. You should copy this sheet before turning it in.
Although students will work in groups of two, each student must take individual measurements of distances, angles, paces, period, and accelerations for their ride.
At the Fair
Equipment to take (per person): Data Record and pen
Horizontal and vertical accelerometers
Appropriate clothing for possible cool or wet weather
(per group): Watch or stopwatch that can be read to tenths of seconds

1) Time Measurements: These usually involve measuring the period (time per rotation) of the ride. Find the time for several consecutive rotations for greater accuracy. Take at least two trials per person. What mark or part of the ride's structure did you use as a reference point for counting rotations?
Reference point _______________________
No. of rotations _____________ Total time (s) ______________ period (s) _____________
No. of rotations _____________ Total time (s) ______________ period (s) _____________
2) Distance Measurements: These involve such measurements as height, radius and circumference. Do not use any measurements that you do not measure yourself. Draw a LARGE diagram on the next page on which you indicate all distances and angles measured. Give distances in paces and indicate meters per pace.

3. Accelerometer Measurements: Some rides require measurements of acceleration from various locations. Record all measurements. Include
1) how and where you held the accelerometer, and
2) the direction of the acceleration.

For the horizontal accelerometer, tell the angle of the center BB from the vertical.
For the vertical accelerometer, tell the number of g's to the nearest tenth (include sketch).
4. Tilt Angles: Some rides have slopes or tilts that you will need to know in order to complete your analysis of the ride later. If in doubt whether you need to know a particular angle, go ahead and measure it. Briefly discuss your measuring method. Draw a diagram clearly showing the angle(s) measured:
