![]() ![]() The accepted value for g (gravity) is 9.8 m/s/s, and all the calculated accelerations from the first five runs are within.021 m/s/s higher than the slope estimated from the velocity vs. This makes sense considering this value is only. Run 5’s average acceleration, according do its acceleration vs.The average of all the slopes was 9.762 m/s/s. The maximum slope was run 4’s 9.843 m/s/s. The minimum slope for the first five data runs was run 1’s slope of 9.663 m/s/s.To avoid damaging the Picket Fence, make sure it has a soft surface (such as a carpet) to land on. The entire length of the Picket Fence must be able to fall freely through the Photogate. ![]() Fasten the Photogate rigidly to a ring stand so the arms extend horizontally, as shown in Figure 1. Logger Pro will make two graphs of displacement/time and velocity/time, by solving the slope of the graph we will have the acceleration of gravity.ġ. As we drop "a clear plastic with evenly spaced black bars on it, called the Picket Fence" through Photogate, it will calculate the amount of time the light beam from the device being blocked and send the data to Logger Pro, which we used in Lab 1. In this experiment, we use a device called Photogate, which has a beam of light travel from one side to the other. Today we have an experiment to examine the motion of a falling object and measure the acceleration of Earth's gravity: The basic of the experiment is to have an object "free fall" and then measure the acceleration and give out the result. In Chapter one: Kinematics, one dimension, we have focused in the movement of an object due to gravity. ![]()
