Which term describes the maximum displacement from the equilibrium position during oscillatory motion?

• A. Frequency
• B. Amplitude
• C. Wavelength
• D. Period

Answer: (B)

The term that describes the maximum displacement from the equilibrium position during oscillatory motion is amplitude. In the context of oscillations, such as in simple harmonic motion, amplitude is the greatest distance the oscillating system moves from its central or rest position. This measurement is critical because it directly influences the energy associated with the oscillation; larger amplitudes correspond to greater energy. For instance, in the case of a pendulum or a mass on a spring, the amplitude indicates how far the mass swings from its rest position or how far it is stretched or compressed before it begins to oscillate back toward equilibrium. Understanding amplitude is essential in various applications, such as sound waves, where greater amplitude leads to louder sounds, or in mechanical systems, where it affects the performance and stability of the system. In contrast, frequency refers to how many complete cycles occur in a given time period, wavelength relates to the distance between consecutive points in phase in a wave, and period is the time taken to complete one cycle of motion. Each of these terms plays a role in oscillatory motion but does not represent the maximum displacement from the equilibrium position.
