### VIBRATION

Drs. Supriyono Koes H, M.Pd, MA

Objectives
• To identify themovement of vibration with an experiment.
• To determine theamplitude, period, and frequency of a vibration.
Vibration = Simple harmonic motion

1 vibration = movement from A, O, B, O, to A.

A

B

O

Some definitions
• Vibration is an oscillating movement through a point of equilibrium
• Displacement is any distance between the vibrating thing and its equilibrium point.
• Maximum displacement is called amplitude of a vibration.
• Period (T)is the time needed to do one vibration.
• Frequency (f)of vibration is the number of vibrations which happens every second.
Problems
• Is the period of a pendulum influenced by its amplitude?
• Is the period of a pendulum influenced by its thread length?
• Is the period of a pendulum influenced by its mass?
• DO AN EXPERIMENT
Solving the problem
