    How Should Time and Distance Uncertainties Affect Calculations in Physics Labs?

    The lab deals with uncertainty and significant figures so I can't have more than I need because I'll lose points. Based on the information given, what do you guys think should my 10.0 min and 170.0 min be converted to?

    How Should Time and Distance Uncertainties Affect Calculations in Physics Labs?

    Homework Statement This is a lab question. I'll summarize with key information. Car traveling from Point A to Point B. You record the time and distance. "Since the odometer gave the distance within 100 m, you estimated the uncertainty in d to be (Δd = ±0.1 km). Regarding the time, even though...
