In physics class at Irondequoit High School Students did a lab to show gravity close to the earth’s surface. The students showed that the gravity is approximately 9.73m/s^2. This is a .82% error compared to other research. The students found this out by dropping a ball and timing how long it took for the ball to hit the ground from two meters. As the group of three dropped and timed the ball they recorded the results of the three trials they did. Using the time, distance and initial velocity they found out the acceleration for each time. The group used the kinematics equation ‘d = vit + (1/2)
