FRONTLINE Un(re)solved vs CloudLabs Free practice

Say their names. Know their stories. Who are the men, women and children whose cases were examined under the Emmett Till Unsolved Civil Rights Crime Act? In this augmented-reality experience that pairs with the Un(re)solved installation, explore a living quilt and bring to life stories woven throughout. Learn about a federal effort to investigate racist civil rights era murders and right wrongs of the country’s past. Drawing on more than two years of reporting, thousands of documents, dozens of first-hand interviews with family members, FBI agents, Justice Department officials, and journalists, Un(re)solved investigates the federal government’s effort to grapple with America’s legacy of racist killings through the Emmett Till Unsolved Civil Rights Crime Act — and makes available for the first time a comprehensive interactive collection of stories about the more than 150 people on the Till Act list. The Un(re)solved AR app is to be used when visiting the traveling installation exhibit of the same name. Using your smartphone, you’ll go on a guided journey to learn about the people on the list. A soldier coming home to his wife. A member of the Passamaquoddy Tribe of Maine. A teenage basketball star who was shot in what has come to be known as the Orangeburg Massacre. Louisville’s first female prosecutor. Throughout the experience you’ll be invited to say the names of the victims to bring their stories out of the past and into the present. For the optimal experience use with headphones and increase the brightness on your device. Runs on iPhone 6s (or later) and iPad Pro (2nd Gen) (or later). If unable to visit the Un(re)solved exhibit check out the immersive at-home experience at: FRONTLINE.org/unresolved. Un(re)solved is produced by FRONTLINE and Ado Ato Pictures. The audio conversations were produced in collaboration with StoryCorps. The Civil Rights and Restorative Justice Project at Northeastern University served as an academic advisor. © 2021 WGBH Educational Foundation

In this lab you will find an air rail with two position sensors to measure the start point and end point of movement. For the development of this practice, the student will have the possibility to configure the initial position, the initial velocity and the acceleration. In addition, the simulator allows you to move the sensors along the rail to determine the points where you want to measure the movement, in order to obtain the numerical and graphical results of the movement. It is also possible to visualize the effect of the friction force on the movement by regulating the amount of air that is expelled by the rail.
