Lab Assignment Sheet Exploring Constant Acceleration (Week 3) Model or Topic Explored: We will be looking at the constant acceleration particle model using the IOLab unit. We will be using some of the basic features of the ‘wheel’ on the IOLab unit along with the accelerometer to explore displacement, velocity, and acceleration. Please refer to the pre-lab video for instructions. All answers and graphs may be added electronically. Name: Amy Marchen Date: 10/30/2017 Observables : Rolling down an incline, starts from rest, and moves faster and faster Measureables : Position (x){Ry- feature in IoLab}, time, instantaneous velocity (v){Vy- feature in IoLab], acceleration Constants: Starting position, acceleration, initial velocity, slope of track Problem Statements : 1. How does positiondepend on time? 2. How does velocitydepend on time? 3.How does velocitydepend on position? depends on time (problem statement 2), I predict the graph will be a linear relationship (y=mx+b) with slope being positive and equal to the constant acceleration. When velocity depends on position (problem statement 3) (making it velocity squared), I predict the graph will be a linear relationship (y=mx+b) with a positive slope. Experiment: Procedure, Tools, Diagram of Apparatus: [In this section, please paste a digital photograph of the items used in your experiment.] Tools : iOlab Unit, Computer, Inclined plane Procedure: 1. Gather the tools needed 2. Set up the inclined plane (use a table and books stacked under one side to lift it) 3. Place something at the end of the inclined plane to catch the iOlab unit from falling off the table 4. Turn on iOlab software on computer to record data 5. Start at the top of the inclined plane and let the iOlab unit roll down the inclined plane in the +y-direction while recording the data under the wheel sensor 6. Do not change incline of the plane PHYS 1010 – page 1
Lab Assignment Sheet 7. Zoom in on the data and take the straight line of the data and place it into a table on Excel 8. Set the data table to have an initial time of 0 9. Graph the position versus time data using the data from the “Ry” line from the iOlab 10. Fit the appropriate trend line on the graph 11. Display the equation on the graph 12. Repeat steps 7-11 for the velocity versus time graph
