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 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.

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
