This is a computer lab that utilizes the Atwood’s Machine to explore Newton’s Second Law of Motion, F=ma. To access the lab, go to http://www.physicsclassroom.com/Physics-Interactives/Newtons-Laws/Atwoods-Machine This lab has a total of 34 questions, covering six pages. A calculator is needed, but the math is very straight forward, essentially having the students plug in numbers for Newton’s Second Law of Motion, F=ma. Multiplication and division are all that is needed. Roughly about 30% of the higher-order questions are conceptually based off of the calculations and diagrams the students make in class.
