Kinematics physics lab help sources of error

Click For Summary
SUMMARY

This discussion focuses on identifying sources of error in a physics lab measuring the maximum velocity and acceleration of a runner using carbon tape and a spark timer. Key sources of error identified include the runner's bouncing during the run, which affects the carbon tape's measurements, and potential discrepancies caused by tape friction. The discussion emphasizes the importance of considering data irregularities when analyzing time and distance measurements to accurately determine maximum velocity and acceleration.

PREREQUISITES
  • Understanding of kinematics principles, specifically velocity and acceleration.
  • Familiarity with using carbon tape for motion measurement.
  • Knowledge of spark timers and their function in timing experiments.
  • Basic data analysis skills to interpret time-distance measurements.
NEXT STEPS
  • Research methods to minimize measurement errors in kinematic experiments.
  • Learn about the impact of friction on motion measurement accuracy.
  • Explore techniques for analyzing irregular data sets in physics experiments.
  • Investigate alternative timing methods to improve measurement precision.
USEFUL FOR

High school physics students, educators conducting kinematics labs, and anyone involved in experimental physics seeking to enhance measurement accuracy and error analysis.

1. The problem statement of my lab
I have this physics lab where I have to find the maximum velocity and maximum acceleration of a high school student sprinting/running using carbon tape and a spark timer. Which I already did. Now I'm having trouble developing my sources of error section. I hope that I can get some insight or help that I would really appreciate. My one source of error that I have right now is:
1. The runner bounces during his/her run. This makes the carbon tape bounce up and down like making measurement defects in our lab. (I don't know if this is enough or even right).
(can't think of anymore)

The Attempt at a Solution


I was thinking of maybe the spark timer but the spark timer isn't really a good option I feel. Possible the tape and the friction could leave a discrepancy in my measurements as well?

As I understand it you have a series of (time, distance) measurements.

Some things to consider in addition to the point you made.
How smooth a curve would the data represent? How will you use the data to find velocity and acceleration. How will you find the maximum velocity and acceleration? How might your methods be affected by any irregularities in the original distance-time data?
