Zoheb Noorani Todd Chapman Experiment 2 Introduction The purpose of this lab is to prove Newton’s theory of gravitation. The theory states that as an object gets closer to the Earth it experiences a constant acceleration. We will accomplish this by using a glider on a frictionless surface and measuring the time it takes to travel a certain distance with only gravity as the acting force on the glider. Our hypothesis is that Newton’s theory of gravitation is true and objects experience a constant acceleration as it approaches the Earth. Conclusion Upon completing this experiment and analyzing the data we find out that Newton’s theory of gravitation is true. Based on all the data we notice that all the times are within a few hundredths of a second. You can also see that the standard deviations for all the times are really small numbers which means that all of the times are really close together meaning that there is a constant gravitational force on an object as it

Unformatted text preview: approaches Earth. From Newton’s theory of gravitation we know that the average acceleration of gravity is 9.8 m/s 2 and according to my result I found that my acceleration was 10.39 m/s 2 . Looking at the times for position 1 you can see that the time that it takes for the slider to go through photogate 1 was ranging from .1870 and . 1875 seconds which firmly displays the fact that there was a constant acceleration on the glider. In this experiment we also found that if we use 9.79 m/s 2 as the acceleration of gravity we find that the theoretical acceleration down the track is 5.69 m/s 2 . In this experiment some of the errors that could have altered the results to this experiment are that sometimes the photogate would start reading the values early and the index card on the slider got bumped at one point which could have changed the length of the card could be misread....
