Introduction:

This lab was designed to test us on our ability to use the formula for speed based on data collected in a natural environment that we used to conduct this experiment. By collecting the speed of ten different cars with two stop watches, we have data that we will use to work with the formula.

 

Procedure:

  1. Measure a distance along the side of a road between two set points.
  2. Gave two people stop watches.
  3. Start the stop watch as a car passes the first point; stop the watch as it passes the second.
  4. Record the time it took for the car to cover the distance, making sure you get the data from both stop watches.
  5. Calculate the average speed of each car using the two times you recorded.

 

Calculations:

                Speed is the measurement of how long it takes an object to move a certain distance. In this case, we measured in meters per second. If v=(d/t), then in this case, v=(m/s).

Conclusion:

 

 This lab left us with results that could only have been expected. The cars crossed a distance of 24.3 meters, the time it took them  varying from about 6m/s to about 12m/s. Our results showed that most of the cars were going at about the same speed, or the most part.
