Lab Assignment 1: Linear Motion Instructor’s Overview This lab experiment focuses on freely falling objects. We developed the kinematic equations for freely falling objects in Chapter 2, section 2-7. Please also revue the tutorial on “Falling Objects”. Now we will have an opportunity to directly experiment with free fall and apply our quantitative knowledge of kinematics. This activity is LOOSESLY based on Lab 4-1D of the eScience Lab kit. However, we will be performing a Modified subset of the eScience experiments and all of the procedures and required analysis are contained in THIS document. You may copy this document, add your data, calculations, analysis, and submit as your report. Our lab consists of two components. a) In experiment 1 you will drop a single object, a hex nut for example. You will measure the distance to drop, in meters, with 2.0 meters being a reasonable distance. Then you will drop the object and measure the time to hit the floor. Ten trials will be recorded. b) In experiment 2 you will drop two strings of hex nuts, listening to the interval of time between the impacts. The first string will have 6 hex nuts evenly spaced. The 2 nd string will be made with 4 hex nuts but unevenly spaced – you will untie the first string to make the 2 nd string. This document serves as your lab report. Please include detailed descriptions of your experimental methods and observations. EXPERIMENT 1: Time vs Distance of a Dropped Object. Reference: Section 2-7 in your text. Theory : When a object is dropped the magnitude of its velocity (speed) increases as it is accelerated by the force of gravity. Assuming air friction is negligible all objects will have accelerated (increase their speed) by 9.8 m/s every second.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
