As shown in Figure OQ10.7, a cord is wrapped onto a cylindrical reel mounted on a fixed, frictionless, horizontal axle. When does the reel have a greater magnitude of angular acceleration? (a) When the cord is pulled down with a constant force of 50 N. (b) When an object of weight 50 N is hung from the cord and released. (c) The angular accelerations in parts (a) and (b) are equal. (d) It is impossible to determine.
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
