Pendulum Lab

Question: What are the factors affecting the swing of the pendulum?

Hypothesis: The effects of
1. the weight
2. the height of the release3. the length of the string


Experiment #1
• Hypothesis: As weight increases, the time will stay the same.
• Procedure: We will attach a string to a stand. At the end of thestring, we will attach a weight. We will then release the string and the weight, and we will let it swing through the air. We will time how long it takes for the weight to travel through the air andreturn to the starting point. After we record the data, we will replace the original weight with one of a different mass. We will repeat this process three times.


|Trial |Mass(grams) |Time (seconds) |
|1 |10 |1.25 |
|2 |20 |1.16|
|3 |100 |1.31 |
|4 |200 |1.32 |





Experiment #2
•Hypothesis: As the height of the release increases, so will the time.
• Procedure: We will test the time a 100g weight attached to a string takes to swing and return to its original position. We willthen raise the height of release and test the time, and then we will repeat two more times.


|Trial |Height of release (centimeters) |Time (seconds) |
|1|20 |1.16 |
|2 |30 |1.16 |
|3|40 |1.12 |
|4 |50 |1.22 |
