Domino Effects Lab
Purpose: The purpose of this lab was to see if the speed of the falling dominoes would differ if we changed the spaces of each single domino.
Equipment/Supplies:
1) Dominoes
2) Ruler
3) Camera
4) Stop watch
1) Dominoes
2) Ruler
3) Camera
4) Stop watch
Procedures:
1) Set up 50 dominoes in a straight line (whatever spacing you want)
2) Measure the length of the entire line
3) Measure the length of a domino
4) Measure 3 different spacings between 2 dominoes, then divide by 3
5) Measure the middle of the first domino, to the middle of the last domino and divide by 49
6) Record the falling of the domino, while recording the time
7) Repeat the process 6 times

Analysis Questions:
1) The average speed of an object is defined as the distance traveled divided by the time elapsed.
2) The factors that affect the speed of the dominoes falling are the spacing that are between each domino.
3) The domino only goes from standing still to hitting the next domino, doing an average. We don’t use the instantaneous speed, because then each spacing will have to be the exact same, and that would be nearly impossible, and if not, a long time to do, so instead we use the average speed.
4) Maximum Toppling Speed: 4 Seconds
Minimum Toppling Speed: 1 Second
5) Maximum: 0.68
Minimum: 0.50
6) Minimum toppling speed
53.5 cm/s x 60 s = 3210 cm
Maximum toppling speed
100. cm/s x 60s = 6000 cm

Calculations:
Trial 1: 102.5cm/ 2.55sec= 40.2 cm/s
Trial 2: 104.3cm /2.85sec= 36.6 cm/s
Trial 3: 101.2cm/ 1.40sec= 72.3 cm/s
Trial 4: 82cm/ 1sec= 82 cm/s
Trial 5: 116.5cm/ 1.31sec= 88.9 cm/s
Trial 6: 212cm/ 4sec= 53 cm/s
Trial 1: 102.5cm/ 2.55sec= 40.2 cm/s
Trial 2: 104.3cm /2.85sec= 36.6 cm/s

Trial 6: 212cm/ 4sec= 53 cm/s
Conclusion: The purpose of the lab proved that the spacing depends on how small or large you separate the dominos by. The speed changed according to the size of the spacing. From what the calculations show, it is shown that the closer together the dominos were, the faster they fall down. The farther the spacing, the slower they fall. The longer the line of dominos, depended on the spacing, as well. In conclusion, everything led up to the lay out of dominos.
