/ Physics 295 Introductory Laboratory I Working with the iMac The experimentation that you will conduct in this laboratory will differ from that done in a .conventional laboratory. In older laboratories, much time is spent in laborious data taking, and not nearly as much time is spent in assessing what the data represent in terms of the physics of the events which were observed. In this lab, computer-based tools will be used to collect data and to do much of the analysis. You will thus have more opportunity to give careful thought to how the results of the Activities that you carry out relate to the physics principles that you are studying. The computer platform will be an Apple iMac running version 8.6 or version 9 of the Mac Operating System (MacOS). These computers were added to our lab for the Spring 2000 semester. Obviously, they are now getting old by most computer standards. They do typically serve their purposes well, and we ask you to try not to treat them roughly. We have tried to update the lab manual consistently as equipment has changed; however, due to the scope of the changes, it is likely that we have missed some corrections. Please be patient with small flaws and point them out to your instructor. Attached to the iMac will be a Universal Laboratory Interface (ULI) device that will allow you to use various probes to take and record data for study. Since many people have not used these tools before, today's lab will be used to familiarize you with some basic procedures that will enable you to work smoothly in later sessions. The workstations are connected electronically to each other and to a laser printer. Each of the computers in the lab network has a name so that information can be transferred when necessary. (Each of the names used is that of a person who was an important contributor to the study of physics.) There are eight active workstations that will usually serve three persons each. The Teaching Assistant will give you instructions concerning how many persons are to be at a workstation in the section that you are attending. Objectives: in today's lab, you willieam · use of the computer and mouse, · use of the Universal Laboratory Interface with the Logger Pro software, · use of the ultrasonic motion detector, and · use of the force probe. Macintosh Basics The main objective of this and the following sections is that everyone in your group should be comfortable performing basic tasks on the computer. Students who are familiar with PCs running Windows will find there are really only few minor differences between Macs and PCs. We assume that most students are familiar with the most basic tasks of pointing, clicking, double-clicking, dragging, opening and closing files, and the like. If you are NOT, then please ask the TA to help you start the Mac as Tutorial program. The TA will
