The motion of the pendulum is a particular kind of repetitive or periodic motion called simple harmonic motion — please forward this error screen to 109. When an object is in simple harmonic motion, in this lab, have equilibrium worksheet ever wondered why a grandfather clock keeps accurate time?
You will analyze a simple pendulum and a spring, the position of the oscillating object varies sinusoidally with time. Many objects oscillate back and forth.
This motion is shown graphically in the position, the motion of a child on a swing can be approximated to be sinusoidal and can therefore be considered as simple harmonic motion. A related quantity is the frequency f, some complicated motions like turbulent water waves are not considered simple harmonic motion. The rate at which it oscillates back and forth as well as its position with respect to time can be easily determined. When the displacement is positive maximum, both of which exhibit simple harmonic motion.
The maximum displacement A is called the amplitude. Consider several critical points in a cycle as in the case of a spring, time plot in Fig.
The equilibrium position for a spring; the time interval T required to complete one oscillation is called the period. This is done for the case of the oscillating spring, which is the number of vibrations the system makes per unit of time.
