Condition :	Good
Principle :	Simple Harmonic Motion
Area of Study :	Acoustics
Equipment :	Spring on Vertical Stand, Masses (set).
Procedure :	Place the desired spring on the support and add an appropriate weight. This system can be put into motion into two ways. One way is to just pull down on a spring and release and watch it move up and down. The other way is to pull it sideways and to release it like a pendulum.
