Course: Pendulum Measurements
Device # 1 Lesson # 1
Does the Entire Pendulum impact the number of swings?
•string, recording, washer
•Meter stick, conventional paper, pencil
I are doing a research to find out if the length of a Pendulum will certainly affect the quantity of swings. We all usually see pendulums in Grandfather clocks. It is the fat that shots back and forth. I will be changing the length of the string, but by no means the weight.
I am going to declare, that while accomplishing this experiment that as the length of the string decreases, the speed of the pendulum will increase.
1 . Got my personal string and measured the lengths. I actually marked the string for 80c, 70cm, 60cm to 30 cm. This makes it much easier to keep functioning. 2 . Discover a table that has a hang over on the side. By doing this the pendulum can move freely. several. Tape the string to the top of the stand. Tie a knot at the conclusion of the thread and place the washer inside the knot. 4. Get someone to help you with the stop watch. Collection it for starters minute. Right now, pull the string again at 10 cm and let go. Usually do not push the pendulum allow it move freely. Rely the complete shiifts out and back makes one finish swing. five. Write down the number of swings each minute.
six. Contiunue right up until you have come to the 40 cm tag.
The pendulum experiment gave the next results.
Pendulum Length Range of Complete Move in one small
almost 8 swings in 14 secs
70 cm 9 swings in 11 seconds
60 cm12 swings in 12 mere seconds
50 cm13 swings in 13 seconds
40 cm15 swings in 14 just a few seconds
30 cm17 swings in 15 seconds
So , from this experiment, I actually am changing the length of the pendulum to determine if the range of swings is going to...
