|Paper Towel Roll Dropped Onto a Bathroom Scale
In this video, a 1.0 kg roll of paper towels is dropped from a height of 0.5 meters onto a bathroom scale. The needle on the scale shows the reading in pounds (force) every 0.001 seconds as the paper towel roll slows to a stop.
When doing calculations, please note that the collision was not perfectly inelastic. The paper towel roll did bounce back up slightly upon impact.
The app for this video has a simplified interface without automated plotting or graphical analysis tools.
Computing Change in Momentum:
Does the total impulse on the paper towel roll match the change in momentum of the paper towel roll? Why or why not?
