1. ### New and Improved Kinematics and Gravity Lab.

New Kinematics and Gravity Lab:

In this new lab we will perform the experiment outside. We could either use a rescue window or go out to the turf and drop the ball from a higher place. In this example you and your group will go out to the bleachers. You will need a stop watch, a ball and a tape measure. To begin the lab you need to calculate the distance from the bleachers to the ground. Using the stop watch, time how long it takes the ball to travel to the ground. You will need to repeat this multiple times to get an accurate representation. After using the information you collected, determine the acceleration of the ball. This new and improved lab will be more fun for the students and cause there to be less marginal error.

2. ### Speeding Lab

The speed limit on Cooper Road in front of Irondequoit High School is 15.6 m/s. However, drivers do not always follow the precise speed limit. We collected specific data to discover the average speed of automobiles driving down Cooper Road. To do this, we measured 50 meters, and marked the 25 meter and 50 meter spots for two individuals to stand at with stopwatches. In addition, one individual stood at the beginning of the 50 meters and indicated when a car drove past them. This would signal to both individuals with stopwatches to start the timer. When the car drove past the individual 25 meters, they would stop the timer, while the individual at 50 meters would continue timing. Then, when the car drove past the individual at 50 meters, they too stopped the timer. This provided us with two different measurements of the speed of the car, which made more detailed data. We repeated this process ten different times to ensure the collection of data on a variety of different kinds of automobiles.

Our results of this lab was that the average speed for a car going down Cooper Rd was 15.21 m/s while the speed limit for Cooper is 15.6 m/s. This said, the average car was going a little bit below the speed limit. There was one exception of a car that was going 20.49 m/s. If we were to do this lab again, to improve our results we would use a radar gun to see the speed because that is a lot more accurate than a person clicking a stop watch which has huge room for human error. Mr. Fullerton’s results for one car was about 12 m/s . That was with one car so to have a better range of data he would use more cars next time.

There is not a speeding problem on Cooper road. Our results showed that only 3 out of the 10 cars were going over the speed limit. Showing that there is not a speeding problem in Cooper Rd because a majority of the cars that we collected data for were going equal of just below the speed limit.

3. ### Myself and My Interests

Being an Eagle Scout will help you problem solve and be a great builder for the labs in class this year

Hi Reed, I cant wait to be your physics lab partner

5. ### Physics Intro Assignment

Hi, I am Stephanie and I am a senior. I am excited to start my senior year in high school. I play tennis for the school. I have been playing for three years now on the team. I also play softball for the school. I have been on the school team for my fourth year now. I play pitcher and 1st base. When I am not playing for the school I play in a travel league named Webster Xtreme. I have been playing on this team for my third year. I cant wait to play my last year of tennis and softball for the school.

The reason why I am taking physics this year is because when I plan on applying to colleges, colleges look for if you have taken four years of science. So I thought that taking physics would be the next step. What I hope to lear this year in physics is to obviously learn physics. But I am looking forward to using my math skills to help me understand physics. I am also looking forward to the various projects we do this year. exspecially the iPhone speakers. I hope that by taking this class I learn more about me as a person and as well as physics.
