What This Document Is
This report details an experiment conducted in Introduction to Physics I (PHYS 2100) at Boston College to investigate the coefficient of restitution – a measure of energy retained after a collision. The experiment explores how this coefficient applies to bouncing balls and a popper, utilizing principles of one-dimensional projectile motion and kinematics. It presents data and analysis from multiple methods used to determine this coefficient for various materials.
Why This Document Matters
This report is valuable for students in introductory physics courses seeking to understand the practical application of theoretical concepts like collision dynamics and energy loss. It’s particularly relevant when analyzing real-world scenarios involving impacts and bounces. The report serves as a record of experimental procedures and results, demonstrating how to apply statistical error analysis in a controlled physics lab setting. It’s used to solidify understanding of how to relate theoretical equations to observed physical phenomena.
Common Limitations or Challenges
This report focuses specifically on the experimental determination of the coefficient of restitution. It does not provide a comprehensive theoretical treatment of collisions or delve into more complex collision scenarios (e.g., two-dimensional collisions, inelastic collisions). While error analysis is discussed, it doesn’t offer a general guide to experimental design or error propagation techniques.
What This Document Provides
The full report includes: a detailed introduction to the coefficient of restitution and its theoretical basis; descriptions of five distinct experimental methods used to measure the coefficient; raw data collected for ping pong balls, Nocsak balls, racquetballs, golf balls, and a bouncy ball (presented in tables); graphical representations of data (including ha vs. hb plots and AKE vs. hb graphs); calculations of the coefficient of restitution (e) and associated uncertainties (δe) for each method and material; and a table summarizing the mass of each object used in the experiment. This preview only provides a high-level overview of the report’s content and purpose. It does *not* include the raw data, calculations, graphs, or detailed methodology.
