- For this project we measured the speed of cars on cooper road. We wanted to see whether cars were following the speed limit.
- We measured out 10 meters
- 2 people used stopwatches measuring the time it took for the front of the car to go 10 meters. Also when people were timing the car, another was recording the details of the license plate and color.
- Took the average of the 2 measurements
- Converted our data into meters per second
This is the data we found

- Our results show that people drove from 7.3 m/s – 10.5 m/s and the average was 9.02. If we were to do this again we should not be as visible so that our presence doesn’t alter the speed which people drive at and there should be less people conducting tests so the test takers can see more clearly. These results are quite a bit different from our instructor who didn’t show his presence to the cars and got higher speeds because of it.
- According to our data, there is not a speeding problem on Cooper Road. The data shows that the average speed cars go is well under the speed limit. This could also be due to many of the cars having to accelerate coming from the traffic light they were at. Based on the data, cars may be going too slow on Cooper Road; at least when there’s civilians measuring their speed.

Hello Isaac, I too enjoy watching all kinds of sports. Like you I also thought physics seemed like an interesting science class.

Trevor, I was fascinated by your life. Yours is truly interesting. What specific medical career are you pursuing and how would physics help with that?

My name is Mike Vrooman. I am a Junior at Irondequoit, but have only been a resident of Irondequoit for a little under two years, as I came from Rush-Henrietta. I am half spanish because my mom is from Spain and I even lived in Spain for several years. In the future I would like to be either a sports writer or a police officer because i enjoy talking about all things sports and i have always been interested in trying to help the community to the best of my abilities. That's my life at this point in time.
I am taking physics this year because I always felt it would be the most interesting of the science classes. I'm not really interested in Chemistry and Biology, but physics appeared to include topics I would like to learn about. I like to learn about why things happen the way they do and of course physics is the explanation for that. Physics seems like a cool class and I hope that my thought becomes true.

This just in from Irondequoit High school, we have found the acceleration due to gravity. Physicists Peter Martin and Mike Vrooman discovered this finding with a state-of-the-art lab. Materials consisted of a gator skin ball, a stopwatch, and a meter stick. They conducted the experiment first by measuring a set distance to drop the ball from. Then one of the physicists would drop the ball from that set height and start the stopwatch at the same time. They would stop the stopwatch when the ball hit the ground. They replicated the test several times to filter out the error. Then using the kinematic equation of d=vit + 1/2at^2 and their knowledge of the time it took for the ball to drop, the distance the ball fell and the initial velocity of zero, they discovered that the acceleration due to gravity is a force of 12.6 m/s^2. However fellow physicists informed them that the accepted value was 9.81 m/s^2. They found that their percentage error was 28% and they attributed it to a lapse between the stopwatch and after the ball hit the ground or starting too early.
