Labs for College Physics: Mechanics Worksheet Experiment 3.2-1

 

 

 

Newton’s Second Law and Newton’s Cradle

 

 

 

As you work through the steps in the lab procedure, record your experimental values and the results

 

on this worksheet. Use the exact values you record for your data to make later calculations.
