NEW: Write up just the Data/Graphs/Calculation, Conclusion, and Discussion sections of a lab report for the car-hanging-mass system from last week. I have provided the Theory section and a template spreadsheet. This report will count as 60% of a full lab report. This is due R 10/13 - Note: this needs to be done on computer.	C5 CQ 1,3,4,6; P 32, 83 + PhET below - due W 10/5 Go to PhET's Gravity Force Lab and click the 'Run Now' button, then answer the following questions: Play with the masses by dragging them back and forth. How does the force depend upon separation distance? You do not need to write specific numbers down, just look at the trends. Play with the masses of each mass by adjusting the controls at right. How do the forces change as the massess change? Play with the masses of each mass by adjusting the controls at right. How do the forces on the two masses compare? Is this consistent with what you found for the satellites in orbit above the Earth? Submit these Grav. exercises with this by W 10/5.
