Here's the data you collected on how disks move in different rooms. You may have noticed that different rooms have different deceleration rates. This is because their surfaces are different and different surfaces have different amounts of friction.
The next step is to calculate the rate of deceleration from your measurements.
Click on one of your data lines to display it in the calculation boxes. Perform the calculations and submit your answer. If correct, it will be added into the collaborative graph as a data point, and you'll earn 5 clams!
