Vibration

• If a pendulum is swinging from A then completes one cycle, it will end on A (from A-B-C-B-A)
• If a pendulum moves from B and back to B again it is one cycle
• If a pendulum moves from C, it ends by C-B-A-B-C, or C-A-C
• Amplitude is the farthest possible are achievable.
• Period is T.
• The time for each completed cycle is a period
• Period divided by 1 is frequency
