Speeding Lab- Kelsey, Josh, Cara, Brenda, Kylee

Recommended Posts

 The students were assigned into groups of five with stop watches and a tape measure. They met into groups to discuss a plan on how to determine how many M/s cars go on cooper road. Then the students went outside and were given ten minutes to set up our measurements. After that they wrote down the next ten cars measurements.

 

 

1.) Gather all materials: two stop watches, and measuring tape

2.) Then measure 10 meters

3.) Have one person stand at the starting point, then one person at 5 meters, then the third person at 10 meters

4.) The person at the starting point starts the stop watch and then the second person says "Go" when the car reaches them

5.) The third person records the time of the second 5 meters after they say "Go."

6.)Then average the results

Conclusion: As the cars went from the start to they accelerated. The results of Mr. Fullerton's radar gun were much higher than the groups results. This could be due to delays in starting the timer. The results from Mr Fullerton's radar gun show that all the vehicles but the Ford Escape remained under the speed limit. The groups results, although much lower show that the Ford Escape was the fastest car that passed by. The groups results could be improved by doing more trials to obtain a more accurate average and also extending the meters measured so their is more time to react to the passing by cars.

             According to the results from the lab there is not a speeding problem on cooper. The results show all but one car remained below the speed limit. And the car that was above the speed limit was only .8 above it which is barely over the speed limit. Drivers may take extra caution before and after school hours to keep an eye out for students. There is not a speeding problem on cooper.
