Question

part a

for vibrational motion, what term denotes the maximum displacement from the equilibrium position?

period
amplitude
frequency
wavelength

Explanation:

Define vibrational motion terms

In physics, periodic or vibrational motion is characterized by several key parameters that describe how a system oscillates about a stable equilibrium position.

Analyze the given options

• Period: The time required to complete one full cycle of vibration.
• Amplitude: The maximum displacement of an oscillating particle or wave from its central equilibrium position.
• Frequency: The number of complete cycles or vibrations that occur per unit of time.
• Wavelength: The distance between successive crests, troughs, or identical parts of a wave.

Identify the correct term

The question asks for the term denoting the "maximum displacement from the equilibrium position." Based on the definitions, this corresponds exactly to the amplitude.

Answer:

• period
• amplitude (Correct answer)
• frequency
• wavelength
