Newton’s Law of Cooling Lab Experiment

This experiment was designed to model the process in which thermal energy moves from one body to another. Newton observed that the energy transfer between two bodies is proportional to the difference in temperature between the bodies. The cooling of hot water to room temperature will be observed for the model. Data table: Average room temperature (°C) 30.29 Initial Water Temp (°C) 70.3   Analysis: Newton’s cooling law was given above as: T = T0 e–kt + Troom Match the variables […]

Lab Parts: Evaluating Spring Constants with the Least Squares Method of Data Fitting

Student Researched Lab Experiment to evaluate Spring Constants Introduction In this experiment we evaluated Hooke’s law by measuring the stretch of a spring with incremental masses. A motion detector provided position measurements and the masses were added 100 grams at a time. To calculate the spring constant we utilized the least squares method of data fitting on a Force by distance graph. Samples Calculations Line of Best Fit: f(x) = 0.202x + 16.5 xi-mean height, yi-force of gravity (1) Mean […]
