Domino Lab
Purpose:
The purpose of this lab is to investigate the ways in which distance, time, and average speed are interrelated by maximizing the speed of falling dominoes.
Procedure: (each step is completed 6 times for each of the trials)
1. Set up 50 dominoes in a straight row with equal spacing between them
2. Measured the total length of rows of dominoes
3. Computed the average spacing distance between dominoes by measuring the length from the middle of the first domino to the middle of the last one
4. Measured the length of a domino
5. Measured the time it took for each set of dominoes to fall
6. Computed the average toppling speed for each row of dominoes
7. Repeated all of these steps for each trial
8. Graphed the data of each trial
Analysis
1. Average speed is a measure of the distance traveled in a given period of time
2. The distance between the domino's and their relative position
3. The domino only goes from standing still to hitting the next domino, doing an average
4. Max: 120.4 cm/second
Min: 50.6 cm/second
5.
6. 120.4 x 60 s=7224 dominoes
50.6 x 60 s=3036 dominoes
Conclusion (Adrian Rega)
The purpose of this lab was to investigate the ways in which distance, time, and average speed are interrelated by maximizing the speed of falling dominoes. We accomplished this by measuring the speed at which every domino fell, the length between each domino and the length of all the dominos all together. We record all the data and found the average speed of each domino using the formula r=d/t. We completed the lab successfully due to the different rates of each of the dominos.
Conclusion (Tyler Grosman)
In this lab, our group accomplished the task of investigating the ways in which distance, time, and average speed are interrelated by maximizing the speed of falling dominoes. The lab accomplished what I thought it would because we were able to accurately record and calculate the data for the average speeds of our trials through manipulating the falling speeds of each set of dominoes, which was our objective. The data we obtained did not show the results that I was expecting to see. Instead of seeing a pattern in our data due to the constant increase in the spacing of one centimeter and the occasional half centimeter, we observed an odd set of average speed that varied drastically as each trial was recorded. I do not feel that our data gives us an accurate conclusion because of the extreme variations in our data and I believe that this instance requires more experimentation.
Conclusion Arman
The purpose of this lab was to find out how distance in between each domino affects the rate at which the domino falls. I thought the lab was successful due to fact that we got different rates in which each domino fell if you look above in our data table. I thought this would happen because you are changing the distance part of the formula when you changing the spacing in between each domino.This as well means you are effecting the slope by changing the distance so you get different speeds for each trial. Although I feel like there might have been some errors in the timing and the spacing because the graph did not come out as I thought it would. I feel if we had more accurate data then we would be able to come together with a far better conclusion to this lab.
Conclusion (Nelson)
As the purpose of this lab was to find how the distance, time, and average speed were related in maximizing the speed, this lab did not accomplish what I thought it would. The results were inconclusive and creates a confusion in terms of the goal of this lab. Much more experimentation is needed in order to reach any sort of conclusion. In addition, I believe that human error has a lot to do with our inconclusive results.
