Day 1: ta measurement


Animation of the ta measurement.

Animation will repeat in 5 seconds

Let time = 0 when the pendulum is released from being held over 75 cm. When Time Keeper says "go", the pendulum is released and the watch started. The pendulum reaches its maximum movement when it swings back over 75 cm, and someone says "stop". The Data Keeper should record each trial as ta on the Data Table. Repeat this measurement 5 times.
