3. 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.

4. Activity 2: Experiment 2 1 Coin2 Coins3 Coins Trial 110.70.4 Trial 210.70.5 Trial 31.10.80.4 Average Time to Complete 10 Full Swings10.70.4 Period of pendulum0.10.070.04

5. 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.

6. Activity 3: analyzing  t= √l(4π^2)/980. The longer the length, the longer the period. Length of Pendulum Experiment Period Theoretical Period 180.170.5 240.71.2

7. 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
