Activity 2: Experiment 1
1 Coin 2 Coins 3 Coins
Trial 1 2 1.8 1.2
Trial 2 2.2 2 1.3
Trial 3 2.2 1.8 1.3
Average Time 2.1 1.9 1.2
Period of pendulum 0.21 0.19 0.12
Activity 2: Experiment 1
The weight of the bob affects the period of the pendulum. The length also affects the period of the pendulum. The acceleration also affects the period of the pendulum.
Activity 2: Experiment 2
1 Coin 2 Coins 3 Coins
Trial 1 1 0.7 0.4
Trial 2 1 0.7 0.5
Trial 3 1.1 0.8 0.4
Average Time to Complete 10 Full Swings 1 0.7 0.4
Period of pendulum 0.1 0.07 0.04
Activity 2: Experiment 1
The length affects the period. The longer the length, the longer it takes. The string was shorter than the one in Experiment 1, so the period decreased.
Activity 3: analyzing t= √l(4π^2)/980. The longer the length, the longer the period.
Length of Pendulum
Experiment Period
Theoretical Period
1 8 0.17 0.5
2 4 0.7 1.2
Activity 3: analyzing
When solving the theoretical period, the length in the formula was used. This was not used in the Experimental Period, so the periods were different
