Hello everyone. So this is my first post in this blog. I am planning to upload my notes for classes that I am taking at university this semester. I hope it may be helpful for some of you. AUM - Modern Mechanics - phy100 / phy172 - Fall 2016 - Experiment 1: Air Track Group assessment questions: • There was a graph where we need to find the acceleration. How to find it? We take two points at the graph between velocity and time, then use the rule: acceleration = velocity / time. • Mention some errors that could happen and how to reduce them. Random errors: -Not adjusting ( the height of ) the photo gate properly. - observational errors. - Not adjusting the smart timer. ( I think? When you do not change the number of the photo gate in the smart timer, for example) Systematic errors: - From the smart timer itself. - From the sensor ( that is on the photo gate ) itself. If it did not record. • For the percentage error for the instantaneous velocity Per...
