Lesson Plans: Time that Star! (Day 1, Animation 1)


Time That Star!

Day 1: t2 measurement

Animation of the t2 measurement.

Animation will repeat in 5 seconds

Let time = 0 when the pendulum is released from being held over 75 cm. When the Time Keeper says go, the pendulum is released and the watch started. When the pendulum reaches its maximum movement (roughly over 25 cm) the second time, someone says "stop", and the watch is stopped. Repeat this measurement 5 times, making sure the Data Keeper records each trial on the Data Table under t2.
