Kinetic Energies and Momentum – A Virtual PhET Lab
After completing this lab activity, the students should be able to:
Calculate kinetic energies
Calculate momentum and final velocities
Write a lab report
Lab Report
The lab report must include the following:
Title
Introduction
Experimental Details or Theoretical Analysis
Results
Discussion
Conclusions and Summary
References
ACS Format for Laboratory Reports  (Links to an external site.)
An example of a lab report is given on the following website:
Professor K – sample lab report (Links to an external site.)
Lab Activity
This lab requires you to produce a lab report to, determine “Momentum, Final Velocities, and Kinetic Energy.” This is the “Title” of your lab report.
Read the relevant chapter on momentum and kinetic energy and add an “Introduction.”
You conduct this lab by connecting to the PhET website by clicking on the link given below (or where applicable through the embedded simulation on the lab page):
PhET Interactive Simulations
For this experiment, you use the “Intro” section of the lab. After you click the intro section of the lab, select “Velocity,” “Kinetic Energy,” and “Values” boxes (upper right-hand corner). Then, move the “Elasticity” scale to 100% elastic. Then check the box “More Data” (bottom left-hand side). Now all the values will appear on the screen.  Now you can change the mass values and the initial velocity values as per the scenario given below, and kinetic energy, momenta, and velocity values will appear on the screen. This information constitutes the “Experimental Details” section of the lab report. You must keep a record of all the values appearing on the screen as experimental values for the scenario. These values form part of the “Results” section of the lab report. Now, complete the theoretical calculations of kinetic energy, final velocities, and momenta for each scenario using relevant equations. These calculated values also form the “Results” section of the lab report.
Now, you can complete the “Discussion” section of your lab report by comparing the values and discussing any differences in the theoretical and experimental values and any other information relevant to the experiment.
Complete the lab report by adding a summary to the “Conclusion” section of your lab report.
Submit the lab report to the relevant Canvas Dropbox
