Free Fall Lab Report

Decent Essays
Gravity is responsible for a number of things such as our weight, rainfall, the turning of the planets, and why objects fall. Proven already, that if an object is in free fall the only force active is gravitational force. And when force is thrown into the mix and acts on gravity it cause an object to accelerate or speed up. Hence the purpose of this lab is to prove that an object under the impact of gravity will accelerate at a constant rate. Acceleration will also be measured and compared to its actual value 9.8 m/s^2 , the value is negative because gravitational acceleration is downward and noted by as a=-g. It is predicted and expected that the outcome for this lab is that the ball free falling would have a negative velocity and then become…show more content…
This software assists in achieving the change in the position and determining the velocity. Once completed a plot was created to obtain a slope. The slopes on the graph are linear, and the points plotted fall on the line of best fit. The acceleration due to gravity for the free falling ball was measured to be 10.697 m/s^2 and 9.997 m/s^2 for the bouncing ball. The values are relatively close to the actual value of 9.8 m/s^2 . Once g values were obtained a percent error was calculated. For the free falling ball the error came out to 9.15% and percent error of the bouncing ball was 2.01%. Evidently from the percent errors there was not much error during the lab. Since there is a very small error it could have been from miss reading of the balls position or human error. Overall the lab was a success. The goal of measuring the acceleration due to gravity was achieved and the values received were relatively close. The predictions that a ball free falling would have negative velocity and then become even more negative and that a ball bouncing is expected to bounce up and have a positive velocity, then become negative were accurate and proved
