NEWTON’S 2 nd LAW – LAB WORKSHEET Name: Partners: TA: OBJECTIVE EXPERIMENT #1 – CONSTANT SYSTEM MASS Label all values with appropriate units! Mass of the S-hook Run Mass on hanger Acceleration 1 2 3 4 5 1. What physics quantity does the slope of the velocity vs. time graph represent? 2. What does the slope of the acceleration vs. applied force represent? See step #13 in the manual. 3. What is the experimental value of the total mass of the system and it’s corresponding uncertainty? m total = ∆ m total = 4. Use the digital scale to measure the total mass of the system (cart, hanger, weights, and string). This is the theoretical value of total mass, m 0 . Calculate the percent discrepancy between m 0 and m total and show your work . See step #14 in the manual. m 0 = % = 1

EXPERIMENT #2 – MEASURING GRAVITATIONAL ACCELERATION USING NEWTON’S SECOND LAW Label all values with appropriate units! Run Mass on hanger Moving toward sensor ( a 1 ) Moving away from sensor ( a 2 ) 1 2 3 4 5 5. Show a sample calculation for a avg using Eq. (6) in the manual. 6. Using the value of a avg you just calculated along with the masses you determined with the digital scale, show a sample calculation of gravitational acceleration using Eq. (7) in the manual. 7. Using the mean value of g exp (given to you by Capstone), calculate the percent discrepancy between g exp and g 0 . % discrepancy = | g exp − g 0 | g 0 × 100% 2
