Question

2) Explain the experimental set -up of this lab. What are the dependent and independent variables? 3)Your lab manual states that the accepted value for Gravity at this location is 9.792 m/s2. Why do you think this value is different than thr 9.81 m/s2 sired in your textbook? 4) How does the difference in this value for Gravity affect calculations that require you sto solve for distance? Calculations that involve you to solve for time? 5) How would dropping a more massive ball affect your values for Gravity? Post Lab 1) If your value strayed from the accepted 9.792 m/s2, what experimental errors led to differences in your value for Gravity? 2) what type of errors would you cause your value for Gravity to be to big? 3) what type of errors would cause your value for Gravity to be small? 4) Using the data gathered in this lab, solve for the terminal velocity of your ball as it strikes the sensor for each height. 5) A stone is dropped form a high building and it is observed to take 3.5 secs to reach the ground below. a) Assuming that air resistance is negligible, use the observation to calculate the height of the building. b) In practice, air resistance is not negligible. Is your answer to part A higher or lower than the real height of the building? Explain. M9c: Free Fall Acceleration Introduction: Gravity represents one of the central concepts of physics. In fact, two of the most well koown names in physics found their fame in dealing with gravity. If one were to ask people the first name that pops into their mind when they hear the word "physics", most likely it will be Sir Isaac Newton and his allegorical apple falling from the tree), or Albert Einstein (whose theory of relativity modifies and extends Newton). The main objective for this experiment is to calculate the acceleration 7g of a free falling object manifested due to the force of gravity In addition to this objective, this experiment will also determine if mass or the distance that an object falls influence the gravitational acceleration that object experiences. The question of whether or not heavier objects fall faster will be answered yet again, determining if Galilco's experiments at the Leaning Tower of Pisa were right. This all will be accomplished first by dropping a silver colored metallic sphere from several pre-established heights. Measuring how long it takes the sphere to fall, it is then possible to calculate gravitational acceleration. The effects (if any) of mass on gravitational acceleration are tested by dropping a second sphere, different from the first, and measuring how long it takes to fall. One final component of this lab, found within the Discussion section, will be the demonstration of how the application of key concepts within physics can lead to the derivability of any number of equations, which is a very useful aspect of the study of physics.
