Students participating in an engineering project design the triangular widget seen in FIGURE 12.10. The three masses, held together by lightweight plastic rods, rotate in the plane of the page about an axle passing through the right-angle corner. At what angular velocity does the widget have 100 mJ of rotational energy?
PHYS 1961 SEC 001 September 13, 2016 Group Members: Lab Report #1 Introduction This lab was an introduction to kinematic motion in an experimental setting. Its purpose was also to walk us through with the proper procedures and to set a foundation for future labs. In this lab, we drop a picket fence to record freefall as it passed through the photogate. The photogate sensed the position of the picket fence passing through it during the fall with a beam of infrared light. The data was recorded in the computer program PASCO Capstone which allowed us to easily graph it using Excel, and extract an equation for each formula with bestfit lines which were useful in comparing slopes, that represented the experimental acceleration in each trial. The following two equations were deri
