A. Please watch a short video clip Gravity - "Detached" first. https://www.youtube.com/watch?v=C4pcg7bXgmU This clip from Alfonso Cuarn's 2013 movie Gravity shows rookie astronaut Dr. Ryan Stone (Sandra Bullock) get separated from astronaut Matt Kowalsky (George Clooney) as their space shuttle is destroyed by debris. Before she detached herself, the space shuttle was rotating. What happens to her when she is detached? Does she move in a straight line or on a curved path? B. We will use the metal nut tied to a string to mimic Dr. Ryan Stone's motion. You will do this one the floor. Hold the lose end of the string and rotate the metal nut so that it makes a nice circular motion on the floor. When it reaches a steady circular motion, release the string. What happens to the metal nut? Does it travel in a straight line or a curved path? Does the metal nut eventually stop? What force stops it? What will happen if there is no such force
