![]() ![]() Under Point Symbols, select the shape you like.ĭ. In order to change the shape of the data points, double click on the second column and go to the Options tab. In the Column Definition tab, you can set the name, the short name, and the units for each column. The column names in the data table can be renamed by double clicking on the title columns in the Data Table in the Data window. The data points should automatically be entered into Logger Pro.Ĭ. Enter the data for sinθ (X) and acceleration a (Y). Create a new data table by selecting New Data Set from the Data menu. In order to do this, unplug the motion sensor from CH 1.ī. To plot a graph of acceleration versus height, we will need to enter our data into a new table. Create a graph of acceleration versus the sinθ.Ī. ![]() ![]() Repeat steps 2 through 5 for the five values of your height.Ĭopy the image of ONE of your velocity graphs (with linear fit) for your lab write-up! Data Analysisġ. Take the average of the three runs to get your acceleration.Ħ. Record the acceleration (the slope of the line of the velocity curve for the part of the curve where the cart is accelerating).ĥ. Determine the acceleration for the cart by using the Linear Fit tool and highlighting the appropriate region of the velocity graph. Do not let the cart collide with the end of the track!Ĥ. The motion sensor will not record accurate data for a cart closer than 40 cm (the limit of its near range). This will take slightly more finesse, but the data will be better. Record data during its entire motion back to its starting point.
