Tuesday May 12 Frequency and Period Warm up: (from yesterday’s lab) If you are making a grandfather clock pendulum, should you be most worried about mass, length or amplitude. Why? = NOTES

Due Today – Tick-tock mini-lab (if you didn’t turn it in yesterday) Homework – Frequency and period half sheet

Equations T = 1/f f = 1/T Period for a Pendulum NOTES

If T = 3 seconds, what is f? Example 1: NOTES Ans: Hz

If f = 4 Hz, what is T? Example 2: NOTES Ans: 0.25 sec

If f = 0.4 Hz, what is T? Example 3: Ans: 2.5 sec

Example 4: Monique jumps rope in order to train for basketball season. If the rope hits the ground underneath her every 2.2 seconds, what is the frequency of the rope? Ans: 0.45 Hz

Example 5: Edo plays the drums, and does a drumroll that has a frequency of 12 Hz. How much time is there in between drum beats? Ans: sec

Example 6: Length = 3 meters Gravity = 9.8 m/s 2 What is T of the pendulum? Ans: 3.47 sec

Example 7: Length = 0.25 meters What is T of the pendulum? Ans: sec

Example 8: Jakere pushes her cousin on a swing. If the length of the swing is 2 meters, what is the PERIOD? How can she verify her calculation? Ans: 2.83 sec Ans: use a stopwatch to measure it
