Pendulum patterns
Inventors (Intermediate), mission I1 Forces & Motion, lesson 4 of 6.
Hook
A pendulum always keeps time. Can we use its pattern to predict the future?
Fair test
Count swings in 15 s for 3 weight positions. Graph it and predict a 4th position before testing.
Bonus challenge
Set the pendulum to exactly 60 beats per minute: a one-second clock!
