Liquid Film Motors [pic] Fiona McLaughlin Zoe Cheng Loreto College Coleraine Comments Abstract We have carried out an experimental and theoretical study of liquid film motors. This phenomenon was first reported in 2009. Two papers have been published on arXiv.com‚ the first describing the phenomenon (Shiryaeva et al)‚ the second offering a theoretical model for the observations (Amjadi et al). The

ello Doc Al and others. I am progressing along with my on-line basic physics course. I completed a new module and have some assessment questions to answer. Please review and let me know the ones that are correct. Those that are wrong just a little clue as to where my thinking process went a stray. I will add my thought process to the ones that I missed telling how I came up with the answer that I did. Thanks for taking the time to assist me on some basic questions. 1. What is the rotational speed

any orientation. Although this orientation does not remain fixed‚ it changes in response to an external torque much less and in a different direction than it would without the large angular momentum associated with the disk’s high rate of spin and moment of inertia. The device’s orientation remains nearly fixed‚ regardless of the mounting platform’s motion‚ because mounting the device in a gimbal will minimizes the external torque. The examples of the application of gyroscope is in inertial navigation

Life Changing Moment Ever since I can remember I spent almost ever y day at my Grandparents house. They live right down the road from my family and me‚ and that is how they got the title “Grandma and Grandpa down the road”. They lived in a small house three bedrooms‚ one bathroom‚ and a small living room with a fire place that can worm the coldest heart. And in their back yard stood a shed filled with old farm equipment and stray cats with their kittens that I would try to catch every day. They

I. Introduction Physics is the natural science that involves the study of matter and its motion through space and time‚ along with related concepts such as energy and force. More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy. Over the last two millennia‚ physics was a part of natural philosophy along with chemistry‚ certain branches

Like many before me one of my most defining moments came from my high school days when I was still attempting to find a balance between getting good grades and maintaining a social life. During that time‚ I was just entering a period where I had dealt with bullying without standing up for myself in school. As a result‚ I entered high school somewhat embittered but also made it intentionally difficult for others to get close to me since many of the people I had once held close to me had turned on
