6. PROCEDURE
1. Gather materials
2. Hang rope from tree
3. Put 4.4 kg weight on rope
4. Pull back to swing line and release
5. Count number of swings in 2 minutes
6. Record data and repeat two more times (3 trials total)
7. Take off 4.4 kg weight and attach 8.8 kg weight
8. Follow steps 4 through 6
7. VARIABLES
CONSTANT VARIABLES- The 2 minute swing time,
length of rope, and how far pulled back
INDEPENDENT VARIABLE- The 2 different weights
DEPENDENT VARIABLE- The number of swings
10. CONCLUSION
Does the weight of a pendulum effect the
number of swings it completes in 2 minutes? A
weight with a greater mass requires more of a
push from gravity to accelerate. So being big
balances itself out. The weights fall/swing at the
same rate because the acceleration due to
gravity is the same for both. My hypothesis is
wrong. I predicted that the bigger weight would
swing more, but they complete about the same
number of swings.
