Ball Down Ramp is motion symme

When you observed the single-domino system with the domino under the right, then under the left end of the ramp, did your evidence support the hypothesis that the left-right and right-left motions were symmetric? Why would we expect that, if the system was set up according to instructions, they would or would not be symmetric? If your results are contrary to your expectations, explain how this might have come about. Include a copy of your data related to this question explain specifically how that data is related to your answer.

• No, from my observation I can conclude that the left -right and right-left motions were different. I made this conclusion from my obtained data:

My report of 5 trials each way for 1 domino

First results with one domino:

1.844

1.844

1.781

1.797

1.781

Reverse system's results:

1.531

1.531

1.547

1.563

1.578

• I can see that the reverse system has smaller time intervals. It means that the second system had larger slope than the first one. It could happen because the surface of the table which I used for the experiment wasn’t perfect. In the first case, the end of the ramp with one domino was lower than the opposite end of the ramp. If the table’s surface was perfect, I would obtain the equal results of time intervals.

Angular Velocity of a Strap

Yes, the angular velocity of a strap changes as the strap rotates. I can see it from the data I have obtained. I repeated the same trial 8 times and got different angular velocities. It means that the angular velocity of a strap changes as the strap rotates.
