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).

Varying Acceleration plots (Using the expression evaluator): Let's consider an arbitrary equation of motion where the position is described by the following equation: x(t) = -5m +7.2-t - 2.4-at2 + 0.2 -+3 This is just an arbitrary function representing a continuously changing acceleration. In this case we could go through the math and show that: v(t) = dix dt -=7.2- -4.8-t+0.6-+2 dv d'x a(0) =- dt $2 -3-4.8-+12-t 4. Reset the simulation 5. Open the Expression Evaluator and type x(t) = -5 + 7.2*t - 2.4*1*t + 0.2*1*t't in the expression evaluator. 6. Run the simulation until the person runs into the brick wall on the right. Q17. Which of the following statements is true of the position at t = 1.()s a) The position is decreasing at a rate increasing in magnitude. b) The position is increasing at a rate increasing in magnitude. c) The position is increasing at a rate decreasing in magnitude. d) The position is decreasing at a rate decreasing in magnitude Q18. Which of the following statement is true of the velocity at t = 1.()s? a) The velocity is positive and the person is speeding up. b) The velocity is positive and the person is slowing down. c) The velocity is negative and the person is slowing down. d) The velocity is negative and the person is speeding up. Q19. Which of the following statement is true about the number of times the position, velocity and acceleration graphs pass through zero? a) Velocity = Position > Acceleration. b) Velocity > Position > Acceleration. c) Position > Velocity > Acceleration. d) Position = Velocity = Acceleration. e) None of the above are true
