Question

Awood's Machine EXTENSIONS 1. Draw a free body diagram of and another free body diagram of Using these diagrams, apply Newton's second law to each mass. Assume that the tension is the same on each mass and that they have the same acceleration. From these two gustionsfind an expression for the acceleration of min terms of m m and Compare the expression to your result in Step 5 of Analysis (Attach sheet) For each of the experimental runs you made, calculate the expected acceleration using the expression you found with Newton's second law of motion and the specific masses used. Compare these figures with your experimental results. Are the experimental acceleration values low or high? Why? 3. An unknown mass can be placed on one side of the Atwood's machine. Using lab measurements and any necessary calculations, the mass of the unknown can be determined. Try it. 5. How does the tension in the string change as the masses start to move? Or does it?
