Jasmine17 posted a topic in Labs and ProjectsThis afternoon at Irondequoit High School, students found the acceleration of a ball dropping from the ceiling. The students then compared their acceleration of gravity to the accepted acceleration of gravity (9.81 meters per second squared). In order to do this one student held the ball at the student, as another measured the distance from the ball to the ground. The student holding the ball also used a stop watch to calculate how long it took the ball to drop to the ground. After doing this about three times, the students used each trial to calculate the average time. Then they used the time in a kinematic equation to find the acceleration of the ball (d=Vi*T+1/2*a*T^2). Once the acceleration was found, the percent error equation was used to find the error between the acceleration found and the accepted acceleration.

Nate, Ed, Dezhaire, Jasmine, Mary Mary Deng, Deâ€™Zhaire Bennett, Nate Moore, Ed Seiffer, Jasmine Fantauzzi This project consisted of our group taking two stop watches and timing the time it takes from one car to reach point 1 to point 2. The problem we are trying to solve is how many people speed down Cooper rd. in front of the school. To figure out this problem our group timed how long it would take each car to travel a specific distance, chosen by our group. Procedure: Go outside Pick distance and measure the length of said distance Decide each personâ€™s job to execute lab (timers, data keeper, make and model keeper, etc) Choose one car to start project, and use the next 9 consecutive cars for data (times to distance) Make sure each time aligns with the car youâ€™ve chosen Conclusion: We concluded that each car stayed within a span of 3-4 seconds. This leads us to believe that all the cars we took data for managed to keep an average speed along the road. Our groups had many issues that made this project difficult at first. To improve our data if we were to do the project again, we would have to have a better communication amongst our group members. Also, we needs to hold a better attention on what each car is so there is more order within our lab. Our average speed, compared to Mr. Fullertonâ€™s speed, is slightly lower, but the discrepancies are not major. According to our data, there is not a speeding problem on Cooper. 35 mph converts to 15.6 m/s, which was above all of our average speeds. The Average speed of our data remained under 15.6 seconds for every car, proving that we do not have a speeding problem. Cooperâ€™s average speed with cars going by the school is below average, when students are out.
