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.
This lab is designed to have students construct balloons and have them race down fishing line to explore the conversion of potential energy into kinetic energy, Newton’s 2nd and 3rd Laws of Motion, and the equilibrium of forces. The lab is 4 pages long with detailed, easy to follow instructions, that should allow the students to seamlessly complete the lab with little teacher redirection. But in reality, at least with my students, they need to be kept on-task whenever they perform a lab.
