    Study Notes

    Definition of Oscillation

    • Oscillation refers to the repetitive back-and-forth movement of an object around a central equilibrium position.
    • Examples of oscillation include the swinging of a pendulum and the vibrations of a guitar string.

    Amplitude of Oscillation

    • Amplitude is the maximum displacement of an oscillating object from its equilibrium position.
    • It indicates the extent of the oscillation; larger amplitudes result in greater distance from the equilibrium state.

    Frequency of Oscillation

    • Frequency is the number of complete cycles of oscillation that occur in a unit of time, typically measured in hertz (Hz).
    • Higher frequency indicates rapid oscillations, while lower frequency represents slower oscillatory motion.

    Period of Oscillation

    • The period is the time taken to complete one full cycle of oscillation.
    • It is the reciprocal of frequency; as frequency increases, the period decreases.

    Restoring Force in Oscillation

    • The restoring force is the net force that acts to bring an oscillating object back to its equilibrium position.
    • It is typically proportional to the displacement from the equilibrium, as seen in Hooke’s Law, which states that the restoring force is equal to the negative product of a spring constant and the displacement.
