Domino Effect Lab Report

Then the dominoes were tipped over, the time was recorded and laced on the data sheet. For the first trial (0. 5 CM) the length of all the dominoes were 29. 1 CM. It took . 32 seconds for the tow to fall, the average speed was 90. 9 CM/s. For the second trial (1. 0 CM) the length of all the dominoes was 43. 4 CM. It took . 50 seconds for the row to fall. The average speed was 86. 8 CM/s. For the third trial (1. 5 CM) the total length of dominoes were 57.

3 CM. The row of dominoes took 0. 75 seconds to fall for this trial. The average speed was 76. 4 CM/s. For the fourth trial (2. CM) the total length for the dominoes were 69. 7 CM. It took 1. 00 seconds for the row to all. The average speed was 69. 7 CM/s. For the last trial (2. 5 CM) the total length of the dominoes was 84. 6 CM. It took 1. 37 seconds for the row to fall. The average speed was 68. 8 CM/s. Introduction: This lab experiment involves the measurement of distance and time.

These two factors are very closely related because they are needed in order to find average speed, which is the main objective of this lab. To find average speed one must first measure the amount of distance and object has traveled.

As seen above in he data section there were only 3 formulas added to find all the data. Any other data found in the lab that did not use one of the formulas was found by physical measurement. These were things such as average width of domino, spacing, and row length.

The rest of the data used one of the formulas listed above. First the average distance was needed to determine how close to the required measurement the measurements were, this was done by taking the average domino width multiplied by the number of dominoes. This was subtracted from the row length. And finally all was divided by the number of dominoes minus one.

What Factors Affect The Speed Of Falling Dominoes

Next the average spacing was needed but not in the regular unit of CM. This had to be put into domino length. This meant the average distance between each domino was how much percent of the average domino width. To find the spacing in domino length the average distance was placed over the average width of a domino. Last the speed had to be found. This was done by dividing the row length by the This gave the speed in CM/s (centimeters per second) It is obvious that the experiment would be full of error. It was virtually impossible for a human to space the dominoes exactly . 5 CM, 1. 0 CM, 1. 5 CM etc. Apart.

Also with the timing, the human finger is not exactly the most precise instrument for clocking a row of falling dominoes. Error could also be found in the dominoes themselves. In certain cases high quality dominoes were not affordable. In cases such as these the dominoes were cheap and had very little quality. Some we different sizes, weights etc. Conclusion: The objective of this lab was to find if a row of closely placed dominoes dropped faster than a row of dominoes placed far apart. As seen the data section, it shows that the closer the spacing distance the faster the dominoes dropped. For trial 1, the spacing was 0. M and the time was . 32 seconds. For trial 2, the spacing was 1. 0 CM and the time was . 50 seconds. For trial 3, the spacing was 1. 5 CM and the time was . 75 seconds. For trial 4 the spacing was 2. 0 CM and the time was 1. 00 seconds. And last, for trial 5, the spacing was 2. 5 CM and the time was 1. 37 seconds. Average speed is the total displacement over the total elapsed time. Many factors affected the speed of the falling dominoes. Things such as the lengths of the dominoes, the spacing distance between each domino, the force in which the first domino was pushed, or the weight of the dominoes.
