Pendulumes Hi world
My class is learning about pendulumes. At first I didn't even know that the word existed. Now I know that they can be used in a grandfather clock to measure the number of seconds. After we did the experiment, I changed my opinion on alot of things. First we agreeded that in a controled expermint that we would first change the lengh of the string. First we made it long. We wanted to see if the length of the string affected how many times the pendulume would swing back and forth in 15 seconds. We found out it did. We decided that the longer the string, the fewer the swings, and the shorter the string, the greater the swings. Then we changed the number of washers attached to the string. We started with only one washer then added on more after we had tested it three times. we found out that the number of washers didn't matter at all. It still swung back and forth the same amount of times in 15 econds. That's all I know about pendulumes.
Sincerely, Sabrina
