create calculated column, and find the displacement of the mass using. Calculated columns, curve fits, modeled functions, and some calculated sensors columns. Computer with Data Studio and LoggerPro software, Science Workshop interface with. We then (let the spring pull down with 100-gram mass hanger on it) and click Collect. Transferring Data from LabQuest to Logger Pro 3 or Logger Lite. Open a file called L11E2-2 (Stretching Spring) on Logger Pro, and under the motion sensor setup, select Reverse Direction and also zero the motion sensor with the mass hanger in this position.ħ. Place a 100-gram the mass hanger on the spring, hold it so that the spring is un-stretched.Ħ. Attach a string to the force sensor, then zero the force sensor.ĥ. csv file from either software, but only Graphical. Graphical Analysis Pro expands these features by allowing students to create custom calculated columns and curve fits. The second way to create new columns is to select from the menu ->Data -> New Calculated Column. Graphical Analysis and Graphical Analysis Pro also provide built-in analysis tools, including statistics, curve fits, and calculated columns. Allows the user to define a new function. Next repeat the process by double-clicking on the column header for sin(q air). Checking this box adds a column to the data set that is the calculated value of the fitting function, at each vaslue of the abscisa. Enter the equation to calculate the dimensionless value for the sine of q ac (rad) values that you entered into the Logger Pro column. Calibrating the force censor using zero mass and a 1 kg weight, then remove the weight.Ĥ. Double-click the column header for sin(q ac) to view the Calculated Column Options dialog box. Put a force sensor on the horizontal sensor, and put a motion sensor on the floor facing up.ģ. Using a C-clamp to secure a vertical rod to the table, then mount a horizontal rod to the vertical rod.Ģ. You may also need to produce graphs and perform appropriate fits using the Logger Pro software. Part 1: Determining the value of spring constant.ġ. especially for new calculated columns in data tables. Part 2: Using the value of spring constant to calculate the elastic potential energy of the spring, then determine the total energy. Part 1: Determine the value of spring constant. This lab is actually divided into two parts: The goal of this lab is to prove the theory of conservation of energy which means no matter where the object is, the total energy has to be the same.
