If you did take observations of positions and clock times, how accurately do you think you could determine the positions, and how accurately do you think you would know the clock times?

I think it would be very difficult to make accurate observations at that speed. You would have to be able to observe the clock, objects, and tape measure all at the same time. This would seem to be a very difficult task to perform with any accuracy or certainty.

Did you pause the video in several places?

How can you use observations to determine whether the tape rolling along an incline is speeding up or slowing down?

I watched the pendulum vs. the tape, it appeared that they both started at the same speed, however the taped ended up passing the pendulum as it rolls down the incline. Also, common sense says that the object rolling down an incline will speed up as it continues down an incline.

How can you use your observations to determine whether the swinging pendulum is speeding up or slowing down?

It would be very difficult to use what I observed to determine whether the pendulum is speeding up or slowing down. I think since the clip is so short it’s hard to tell. Again, common sense says that it would initially speed up from the position where it has potential energy to when it starts to slow down as it swings for longer.

Your responses are good, assuming you did not pause the video. Did you pause it? I believe your answers would be more specific if you had.
