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: Tanyitaku Tanyi Date: 2/07/2024 Constants: Initial Velocity Slope of surface Measurables: Position “Ry” Time • Instantaneous Velocity “Vy” Acceleration PHYS 1010 – page 1
Lab Assignment Sheet Observables: IO Lab Unit Rolling down incline Starting from rest with increase in acceleration Problem Statement: How does position depend on time for constant acceleration? Prediction: I anticipate that velocity will exhibit a linear dependence on position, while also showing a linear correlation with time. Additionally, the position is expected to demonstrate a linear relationship with time. . The graph will be a linear relationship (y=mx+b) with the slope being positive and equal to constant acceleration. PHYS 1010 – page 2
Lab Assignment Sheet Experiment Procedure ( list of steps with some detail): I. Gather the required laboratory equipment. II. Position a book under the ottoman to create an inclined surface. III. Utilize the IOLab to gather and record data. IV. Initiate the IOLab's motion from the top of the incline, allowing it to roll down the plane while recording the data into Excel. V. Generate a graph plotting position against time using the collected data from the IOLab device, and apply a trendline with its corresponding equation. VI. Repeat the process for the velocity versus time graph, recording the data in Excel. VII. Create diagrammatic representations of the graphs, incorporating trendlines and equations. VIII. Repeat the experiment, this time commencing the motion of the IOLab from the bottom of the incline and pushing it upward to record the data. Tools and Diagram of Apparatus: [In this section, please paste at least two digital photographs. One with you and your sign containing your name and the date of your experiment, and at least one more of you with the items used in your experiment (preferably while doing the experiment).] PHYS 1010 – page 3
Lab Assignment Sheet Precautions and caveats: We must take precautions to ensure that the IOLab remains secure on the incline to prevent inaccurate data recording. Additionally, we should avoid setting the slope too steep, as it could limit the amount of data we can collect.
