filling out the given table, we record the time for getting acceleration: recording three times for less error. For each trial, we should be careful that swinging and hitting the desk because the interference affects the data. After that, we calculate the average time and the velocity, and then we calculate the expected acceleration and measured acceleration. By expected and measured

PHYS 2211L Name: Jonghyun Lee October 22, 2019 Energy and Atwood`s Machine acceleration, we can figure out the friction. If there is friction, the two accelerations are not the same value. After all, we find the percent difference in accelerations. Analysis (This picture is for part A, B and C.) ( ' s ' onthe picture ¿ ' y ' for the equation ) For all parts, we need to fill out the given table. For filling out the given table, we need some formulas to use forces on the picture. For the kinetic energy (KE), the formula is KE = 1 2 m v 2 , and the formula is PE = mg y for potential energy (PE). For expected acceleration ( a expected ), the formula is a expected = g m 1 m 2 m 1 + m 2 .

    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.
