Unit 1

This is a drawing of a grandfather clock. This represents Unit 1 because we are learning about pendulums and grandfather clocks have a pendulum in them. Most grandfather clocks are the same size because the length of the pendulum needs to be a certain length in order for it to be accurate. The weight can change and it will still be accurate as we learned in the pendulum lab because the mass does not affect the time of the period. Also it does not matter at what angle the pendulum swings because  that too does not affect the time of the period as we tested in the lab. This is why we see many grandfather clocks are the same size but there are the occasional small or large clocks with a proportional pendulum.
