1. Introduction and Theory (1Page)
- Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. The oscillations may be periodic, such as the motion of a pendulum, such as the movement of a tire on a gravel road. Pendulum motion is a motion in which only the direction of motion changes during the motion of an object. It is the movement of an object (pendulum) suspended from a string reciprocating in the same path.
- factor of vibration's system(in pendulum) : frequency, natural frequency, simple harmonic vibration, period, lenght, gravity, single degree of freedom(for small displacement)
※ Derive the equation of motion of the pendulum

2. Experimental method
Tools : vibration experiment device, single pendulum experimental kit(250g, 400g), tape measure, thread and scissors, acceleration sensor, oscilloscope, PC

- Experiment A
1. Set the length of the string to about 400mm and install two types of weights (250g, 400g).
