Free Fall Acceleration Experiment

In the m9c free fall acceleration lab we were to determine if mass or distance of an object falls effect on gravitation acceleration that the object experiences. The experiment was used to investigate the theory weather the heavier the object that it is will fall faster or not. The method that was used to find gravity was through the derived version of kinematic definitions. The overall result in the experiment concluded that distance and mass does not effect on the gravitational acceleration that the object experiences, either a heavy item or light weight item falling at the same point will land at the same time due to gravity. When people think of a physic quote, one that usually comes to mind is what goes up must come down. Simple as that, …show more content…
However, it is now based on Newton’s law of universal gravitation, which says gravity is a force that draws two bodies of mass proportional to each other. In physics, we understand gravity as a free falling object has an acceleration of 9.81 meters per second squared. In this lab we test that if any object, regardless of the mass will fall with the acceleration due to gravity of 9.81 meters per second squared. The balanced equation to solve for acceleration due to gravity is acceleration (m/s²) = …show more content…
The first procedure was to have the two metal spheres measured on the precise laboratory balance and then recorded. A meter stick was then used to measure the distance where the arm was used to hold the first metal sphere that needed to be placed on the long solid rod on top of the first time gate. The computer timing system was then activated and began collecting the times where the metal spheres pass through sensors. As the metal sphere was dropped to the bottom gate/impact sensor, the time interval was then displayed on the computer timing system program. This was conducted three additional times, then again with five different heights, finally repeated with the second metal sphere.
