After observing the 4 videos, I have seen the white tape roll and pendulum travel. The white tape roll will speed up until something stops it from traveling further(in this case when it stops). It would be similar if it was free falling. The object would speed up until it either reaches a terminal velocity or some other action causes it to stop moving. The pendulum moves in an arc-like formation. At the bottom of the arc is when it reaches its maximum speed. When it starts traveling up is the point where it begins to decelerate. The pendulum speeds up faster because it is not limited by the incline on how fast it accelerates. The limit of measuring these numbers is being able to accurately read everything on the video. Everything travels quickly. It would be difficult, but I believe I could get a very rough estimate. To determine whether the tape is speeding up or slowing down, I would attempt to measure a two equal time intervals. Let’s assume I try .25 seconds. The second .25 seconds, the tape covers more distance. This could only mean that the tape is speeding up. I would make a very similar attempt with the pendulum. Unfortunately, it would be more difficult since the pendulum swings at an angle. Every swing is the same time length, but he distance covered decreases.

Very good discussion. However for future reference note the following:
You need to insert answers into a copy of the question, as indicated in the instructions.
The instructions also ask you to pause the video at a number of points. You should do this if you haven't.
You clearly understand what you are seeing and what you would do with the data, so you don't need to submit anything.
&#Let me know if you have questions. &#
