Determine the Linear Speed of a LEGO CAR After observing the car’s motion, you will likely conclude that it moves with uniform speed during most of its motion. Within a series of investigations you will use two tools to collect data and determine the linear speed of a buggy. (1) Stop watch(es) and meterstick(s) (2) Labpro with motion sensor

Method 1: Stopwatch(es) & Meter Sticks 1) Decide as a lab team what procedure you will use. 2) Sketch the equipment set-up. 3) Write an introduction for the data, briefly describing how the data was collected. 4) Collect data for multiple runs. Organize within a data table. 5) Describe patterns that you notice, briefly. Take notes on sources of error. 6) Create a hand drawn graph of position vs. time using your data. Refer to the video online if you need to remember how to format a hand-drawn graph. Don’t forget to introduce the graph and to discuss afterward what it tells you. 7) Learn to use Excel. Create a graph of position vs. time using your data and tape/glue into your notebook. Don’t forget to introduce the graph and to discuss afterward what it tells you.

Method 2: Labro with Motion Sensor 1 ) Sketch the equipment set- up. 2) Write an introduction for the data, briefly describing how the data was collected. 3) Include a rough sketch of the screen to show the general look of the data. 4) Collect data for 5 runs. Organize within a data table. 5) Describe patterns that you notice, briefly. Take notes on sources of error.
