Objective: In this lab exercise we will he investigating the relationship between position, velocity, and acceleration along with the relationship between the graphs of position acceleration and velocity versUs time.. Using simulations, you will he able to drag objects back and forth in one diinension and observe the resulting position, velocityr and acceleration of the object. The simulation also allows you to mathematically enter an equation of position as a function of time. You will be entering several different equations involving position as a function of time and observing the resulting motion. Materials: a This handout In Attendance or viewing the mini-lecture demonstrating the simulation I Computer and Iota-met access to use the following simulation: I. Starting and Exploring the Simulation: Note: The figures shown below as well as the some of the controls may vary depending on the internet browser and hardware you are using. The figures and description below were generated by running the simulation by using: Internet Browser: Google Chrome Version 84.0.4147.135 Hardware: Apple macbook pro Operating System: macOS Monterey Version 12.0.1 Your hardware software do not need to be the same but there may be subtle differences in the response of the controls. For example, when we get to the section of input position versus time graphs I found I need to toggle between a couple of tabs on the simulation to bring the expression evaluator window back into view. I also found I needed to restart the entire simulation to restore scale to full scale on the graphs as sometimes the zoom-out button (magnifying glass with (-) sign inside grayed out.). In addition, once I started the expression evaluator the only way I was able to disable it was restarting the simulation. Purpose: To familiarize yourselves with the simulation along with the various windows and controls. 1) Start the simulation by clicking of the link above or by cutting and pasting the link into your browser. You should get a screen similar to figure 1 below (the annotations in the call out boxes will not be visible. You may also need to increase the size of your browser window to see the entire simulation. You will want to click on the charts tab on the simulation as we will be using this tab for all the simulations in this lab.The Moving Man (2.05 01) Introduction Charts Tabs to select between the introduction and charts screen Special Features including Moving Man, grab to move or expression evaluator use expression evaluator 4 0 meters 4 10 Position For removing block wall stops om/'s Record or playback motion ion gm/s Acceleration Veder Play/Pause Button Record IF F Found Figure 1: Opening screen of PhET Simulation: The Moving Man (2.05.01).

Use record and playback (Note when in playback mode you have an additional slider to adjust the playback speed. II. Record and plot position vs. time and determine average velocity 1. Reload the simulation 2. Ensure you are on the Introduction tab 3. Open the Expression Evaluator 4. In the expression evaluator evaluate x(t) = 7*cos(t) (Note: the x(t) is already to the left of the box. In the box on the expression evaluator you will simply put 7'cos(t) This is simply an equation of periodic motion in which the person will walk back and forth with a varying velocity. Once you have entered the expression in the evaluator click the play button and record the motion of the person for approximately 20 seconds before clicking the pause button. 6. Switch to playback mode and set the play back speed all the way to its slowest setting. 7. Pause the recording every 0.5 seconds and record the position in Table I below and plot the data on the graph to the right of table 1. Include the position at 0 seconds and note you can use the step forward frame by frame if you are finding it difficult to pause on the 0.5 second intervals. If you go too far and miss a number you can always rewind the play back and replay it.
