[Determining g Lab Deliverable]

History was made today at Irondequoit High School, three students determined the accleration due to gravity.  They named the constant accleration due to gravity "g".  The students discovered this after a series of experiments.  The first experiment they conducted involved examining the acceleration of a ball dropped from 2.8 metters.  After three trials the average time it took for the ball to reach the floor was .69s.  From here the students used kinematic equations to determine the acceleration of the ball was roughly 11.76 m/s2.  The students did however determine they had a 19.88% of error.  Never the less the students at Irondequoit highschool made a significant scientific discovery.

As a part of the Irondequoit police department safety project our group was asked to gather data to determine whether or not speeding was an issue on cooper road in front of Irondequoit high school. The speed limit set by the town is 35 mph but we were skeptical about if people actually followed the law. Our project used a pool of 10 randomly selected vehicles and judged their speed based on the time it took them to travel 3 intervals of ten meters. We then took the measures and calculated the speed that they would in miles per hour. This is how we would figure out if the people were speeding down this road or obeying the law.

1. Draw a data table that was big enough for 10 cars and could fit an area for the increments of 10 meters
2. We then laid out our 3 increments 10 meters apart with tape on the side walk parallel to Cooper Rd.
3. We randomly chose one car at a time.
4. Then when the car reached the starting point we would have one person tell us to start our stop watches
5. Then when the front of the car reached an increment the person would stop the watch.
6. We would record all the times onto the data table.
7. Repeat steps 3-6 another 9 times
8. Then we went on the computer and calculated the average speed of each car into meters per second.
9. Then we figured out the average speed of all the cars.

After collecting our data we found out that no one was exceeding the speed limit down Cooper Rd. Our data shows that a lot of the people went under 13.3 m/s. This is well under the speed limit set by the town. We could improve our results by using a radar gun to measure the speed of the cars at that exact moment.

There was not a problem with speeding on Cooper Rd. This was proven by all the results we collected.

wow that's so interesting I like to swim too!

Hello I'm Ian,  I go to west Irondequoit high school and I'm starting my junior year.  I've been playing lacrosse sense the second grade and I hate it more after each year goes by.  I like to snowboard and hang out with my friends.  I also like to scooter.  Scooting is my passion and I hope to make a career out of it. 

 

My reasoning for taking physics is that I thought it would be easier than chemistry for me.  Physics also interests me more than chemistry.  Lastly I thought that physics could aid my comprehension of scooting and the science behind it.
