Option B: Kinematics Scientific Investigation
Before you begin the scientific investigation below, make sure to download the Kinematics Scientific Investigation Report. As you complete this scientific investigation, fill in any needed information on the report template. If you need more information about each section of the report, please visit the Developmental Module.
This scientific investigation is available below or in a printable version.
Introduction
Velocity is the measure of the displacement of an object over a period of time. It is a vector quantity, meaning that it is a change in position that includes an amount and a direction. A convenient way of representing motion, including velocity, is to use position versus time graphs.
Objectives
In this scientific investigation, you will:
Hypothesis
Using the Procedure and Data Collection section below, read through the procedural information for this scientific investigation. For each of the scenarios described in the Procedure and Data Collection section, develop your own hypotheses which describe your expected results. Include sketches or graphics of what you believe a position vs. time and a velocity vs. time graph for each scenario would look like. Record your hypotheses in the Hypothesis section of your Kinematics Scientific Investigation Report.

Data Analysis
In the Data Analysis section of your Kinematics Scientific Investigation Report, create two graphs for each scenario based on the data you collected in your data table. On one graph, plot the time versus position. On the second graph, plot the time versus velocity. In addition, provide responses to the following questions based on items in the simulation and the data that you collected. Make sure to completely answer each question.
Conclusion
Using the Conclusion section of your Kinematics Scientific Investigation Report, compose three to four sentences describing an overall conclusion based on your data. Were your hypotheses true or false, and how do you know? Use the data and notes that you collected from your simulation experience to form your conclusion. Make sure that you include information that you gained from data analysis to support your conclusion.
Experimental Sources of Error
On your Kinematics Scientific Investigation Report, provide responses to the following questions: Are there any sources of error? If so, what are they, and what could be done to minimize error?
