Next, think about a motion from one of the Rube Goldberg machines you observed in the module resources. Choose a particular step in the process of that motion, think about the components of acceleration, velocity, and displacement, and address the questions listed below. As were focusing on one-dimensional motion this week, stick to cases in which the motion may be backward or forward, but also along a line. Include which video you are referencing and the time in which your chosen motion occurs in the video.Is velocity constant? If not, is acceleration positive or negative?Can you estimate this motion?What kind of accuracy is there?
