What does the slope of the time represent? The line on the graph is a straight, diagonal line.
#ACCELERATION DUE TO GRAVITY LAB REPORT DATA USING PHOTOGATE FREE#
Sketch velocity-time graph of a free falling object. M/s2 and the experimental value is the average of the ten experimental value of g from our ten trials which is 9.82 m/s2 Our percentage error is 0.10% which is good because in most cases, a percent error or difference of less than 10% will be acceptable.
#ACCELERATION DUE TO GRAVITY LAB REPORT DATA USING PHOTOGATE TV#
The TV or theoretical value was given by our professor which is 9.81 After the table was finished we then calculated the percentage error.

To calculate the average we add up all the numbers, then divide by how many numbers there are. To finish the table we then computed the average of all the velocity, position, and the experimental value of g of our ten trials that we measured. Getting the experimental value of g of all the ten trials. After getting all the velocity and position of the ten trials we then proceeded in calculating the experimental value of g through this formula g = From these measured times, the GLX Xplorer will calculate the velocities and position for each of the ten trials. We drop the picket fence in the photogate head for ten times for our ten trials. This timing continues as all eight bars pass through the Photogate head. As the Picket Fence passes through the Photogate, the GLX Xplorer interface will measure the time from the leading edge of one bar blocking the beam until the leading edge of the next bar blocks the beam. You will drop a piece of clear plastic with evenly spaced black bars on it, called a Picket Fence. It can detect whenever this beam is blocked. The Photogate head has a beam of infrared light that travels from one side to the other. For this experiment we have to use a precise equipments to measure the velocity and position and that is the GLX Xplorer and a photogate head. In this experiment, first we set up the iron stand and clamp it properly in the table to align the setup properly. We can measure the acceleration due to gravity using a wide variety of timing methods. This acceleration is usually represented with the symbol g. As a result, an object in free fall accelerates downward at a constant rate. When the object in free fall is near the surface of the earth, the gravitational force on it is nearly constant. No other forces can be acting in particular, air resistance must be either absent or so small as to be ignored. We calculate our results from the tabulated data and compare it with the accepted value of 9.8 m/s2.ĪNALYSIS AND INTERPRETATION: We say an object is in free fall when the only force acting on it is the earth’s gravitational force. And also by using the GLX Xplorer to record the velocity and position for each drop of the picket fence through the photogate head ten times. Using a “picket fence” dropped through a photo gate for ten times, with neglect for air resistance. We used the following formulas to obtain the experimental value of gravity: g =Īcceleration due to gravity in a free-fall experiment.

In this experiment we have to determine the acceleration due to gravity of a falling object by measuring the velocity and time of fall of a picket fence dropped through a photogate using Xplorer GLX. When an object is in Free-fall, we will always ignore any effects that air resistance may have on the object’s motion. The constant acceleration of the object is always directed downwards due to the influence of earth’s gravity the acceleration due to gravity on earth is referred to as “g”, and has a value of 9.8 m/s2. Anytime an object moves vertically, either going upwards, or going downwards, we say it is in Free-fall. LABORATORY REPORT Experiment 2 Free Fall Motion Using Picket FenceĪBSTRACT: “Free-fall” motion is a Uniformly Accelerated Motion that takes place in a vertical direction.
