Apparatus: Free-Fall Apparatus Meter Stick Diagram: Theory: Gravity has been discussed for many centuries and it was the Greeks that noticed what the effects of gravity. Many Greek philosophers believed that the planets and stars were part of gods’ realm and that they followed a certain motion (Stanford). It was not until Sir Isaac Newton that gravity was discovered as a part of the motion of the planets. Because Newton’s law of gravity was not disproven, it was considered to be a scientific law. It was until years later that a new theory for gravity was made by Albert Einstein. According to Albert Einstein, gravity is the result of the “warping of space and time (Stanford). Despite all of these improvements, one thing remains the same: the acceleration of gravity and its effect on free falling objects. A freely falling object is an object that only falls under the influence of gravity. The parameters of a freely falling object can be defined as length/distance, time, speed, velocity and acceleration. Velocity is the speed and direction of a traveling object. To find the spe... ... middle of paper ... ...s" Velocity 13: 3.8/.0167=227.5 "cm" /"s" Velocity 14: 4.1/.0167=245.5 "cm" /"s" Percentage Error: (979.9-947.95)/979.9*100=3.26% Conclusion: In this experiment, we analyzed the effects of gravity on a free falling object, and determined the velocity and acceleration of the object through means of different formulas. As we analyzed our data, we noticed that the velocity increased between the different distances. After plotting the graph of the acceleration, we compared the acceleration of the object to the acceleration of gravity; the measurements we achieved were very close to the actual value as our percent error was 3.26%. This means that we finished the experiment with accurate results and understanding if the subject. Works Cited Thompson, H., & Havern, S. (n.d.). Gravity. Gravity.
