Place the larger ball (19 mm) in the release mechanism. Place the free fall adapter’s timing pad on the floor directly below the release mechanism. Mount the free fall adapter’s release mechanism horizontally in the clamp. Attach the right angle clamp to a vertical support rod. When calculating the slope using your paper graph make sure to specify the points you used to do so. Apps for a free fall acceleration due to gravity caused by the acceleration due to gravity. You do not need to calibrate the free fall adapter. Use both graphs to calculate the acceleration due to gravity with uncertainty. Add a labeled table of data to your Excel graph sheet.

(check my video on how to use Tracker) What should we plot to get a linear graph? What are your predictions for the slope and the intercept? Plot your data using Excel (attach a copy of your graph, make sure to label the axis and add a title to the graph). We will be using those data to get the acceleration of gravity. At a customers site the measurements are usually perfor- med with a relative gravimeter, measuring the gravity difference with respect to a point with known. This equation is equivalent to : 2h = gt2 The video analyzer "Tracker" will give the position of your object at different times.
The acceleration due to gravity is a natural phenomenon is represented by the symbol g (italic) varies with location is effectively 9. An object in free fall experiences an acceleration due to gravity. Measuring g When you drop the ball from a certain height, the height will be related to the fall time vis the kinematic equation: h= gt? where t is the fall time. Free fall occurs whenever an object is acted upon by gravity alone.

We will consider the accepted value of the acceleration due to gravity to be: g = (978.03 +0.01)cm/s2 Procedure of time measurement: 1) Choose an object that won't be affected by air resistance ( a marble, a tennis ball, etc.) when dropped 2) Take a video of you dropping the object from a certain height ( around 1.5 m or more) 3) Measure the height 4) Analyze the video with Tracker, a software that is free to download. We will learn how to get the slope as well as it uncertainty from the graph. We will also practice graphing both by hand and using Excel. Air resistance will be neglected throughout this lab. In this lab we will be measuring the acceleration due to gravity by measuring the time it takes an object of your choice to reach the ground. Transcribed image text: Gravitational Acceleration Overview: During free fall, an object accelerates at the acceleration due to gravity.
